USING ELECTRICITY ON THE JOB!
Career Featured: Formula One Drivers
WHAT IS ELECTRICITY?
Electricity is the flow of electrical power or charge.
It is form of energy that results from the existence of
charged particles such as electrons or protons, either
statically as a build up of charge or dynamically as a current.
When electrons move among the atoms of matter,
electricity is created. The electrons are passed from atom to
atom, creating an electrical current from one end to other.
WHY IS ELECTRICITY IMPORTANT?
Electricity has been a vital part of our lives. It has
brought significant contributions to make our
work, lifestyle and careers more efficient and easier.
Electricity powers our light, heating, electronic
appliances such as computers and television, and a host of
essential services such as medical
operations, communication advancement and technology
WHERE DOES ELECTRICITY COME FROM?
Power plants make electricity out of other forms of energy
like hydroelectric power, wind power, solar power, geothermal
power, nuclear power and fossil fuels.
WHAT IS AN ELECTRIC CIRCUIT?
An electric circuit takes place when electrons travel
from the power source through the wires, to the closed
switch then to the load such as a light bulb.
Electricity is related to charges, and both electrons and protons
carry a charge.
The amount of the charge is the same for each particle, but
opposite in sign. Electrons carry a negative charge while protons
carry a positive charge.
The objects around us contain billions and billions of atoms,
and each atom contains many protons and electrons.
The protons are located in the centre of the atom,
concentrated in a small area called the nucleus. The electrons are
in motion outside of the nucleus in orbitals.
Moving Electrons and Charges
The protons are basically trapped inside the nucleus and can't
escape the nucleus. As a result, it is moving electrons that are
primarily responsible for electricity.
The relationship between current, voltage, and resistance
is presented in Ohm’s law.
This law states that the amount of current passing through
a conductor is directly proportional to the voltage across the
conductor and inversely proportional to the resistance of the
Ohm’s law can be expressed as an equation:
Voltage(V) = Current(I)*Resistance(R)
Resistance(R) = Voltage(V) / Current(I)
Current(I) = Voltage(V) / Resistance(R)
WHO USES ELECTRICITY IN THEIR JOBS?
ELECTRICAL ENGINEERS – They design complex power systems
and apply the different principles of electricity.
TECHNICIANS – They use electricity whenever they do repairs
with the use of different devices that are also powered by
NUCLEAR POWER PLANT OPERATORS – They are responsible
for all the monitoring and maintenance of a power plant. They
use sophisticated instruments to monitor all the transmissions
that happen in a power plant.
FORMULA ONE DRIVERS (PROFESSIONAL RACE CAR
DRIVERS) – Formula one drivers use electricity to start the
engines of their car. Formula One drivers use the technology
called KERS (Kinetic Energy Recovery System) and DRS (Drag
Reduction System), which also involves electricity, to boost the
acceleration of their cars.
mmUSING ELECTRICITY TO START AN F1 CAR
Electricity plays an important role in starting a Formula One
At the beginning of a race, a complex system of steps is needed
to breathe life into a Formula One engine.
An electrical starter motor is used to get an F1 car rolling. It is
an external unit which has a long wand that is plugged at the
gearbox. When the mechanic pushes the starter
motor, electricity runs through the gearbox to start the engine.
ELECTRIC CIRCUIT DIAGRAM IN
STARTING AN F1 CAR
Power Source – The electrical starter motor provides the
power needed to start the engine of an F1 car.
Switch – The push button, which is also on the electrical
starter motor, acts as a switch. When the button is pushed, 24
volts are put through the gearbox to turn the engine.
Wire – The wires and the long wand that are on the starter
motor acts as a pathway for electrical energy to flow.
Load – The engine of an F1 car serves as the load of this
electric circuit since it uses electrical power to get itself going.
PARTS THE ELECTRICAL CIRCUIT
KERS stands for Kinetic Energy Recovery System. This
technology recovers the kinetic energy whenever the car
brakes. It stores the energy into a battery and converts it into
power that can be used to boost acceleration.
The KERS system could deliver a maximum of 60kw of energy
and its storage capacity could store up 400 kilojoules of energy.
There are two types of system in which KERS works, the
mechanical system and the electrical system.
USING ELECTRICITY TO BOOST ACCELERATION
KINETIC ENERGY RECOVERY SYSTEM (KERS)
In a mechanical system, the energy produced when the
car brakes is captured and is used to turn a small flywheel.
In an electrical system, the mechanical energy is
converted into electrical energy with the use of a motor –
generator that is incorporated in the car’s transmission.
TYPES OF KERS SYSTEM:
DRAG REDUCTION SYSTEM (DRS)
The Drag Reduction System is essentially an adjustable rear
wing which can be used to facilitate overtaking.
It allows the car to slide through the air quicker by opening a
gap in the rear wing to reduce the car’s drag.
Based on simulation stats’ it appears that the difference
between a car using the DRS and one not using it is likely to be
around 10-12 kph at the end of the straight line where the
DRS can be used.

WHY THE JOB IS IMPORTANT?
The job is important because of these several reasons:
It is a source of entertainment and leisure.
It offers opportunities for foreign investors to invest in
many businesses in the host country of the event.
F1 drivers push the limits of automotive engineering to
They test some of the coolest and newest technologies in
SKILLS REQUIRED TO BE A F1 DRIVER
quick decision-making skills
In addition to excellent driving skills, F1 drivers should also have
the following skills:
INTERESTS A PERSON SHOULD HAVE TO
BE A F1 DRIVER
Interest in cars
Interest in driving
Interest in new and cool technologies
Interest in Go Karting
POSITIVES OF THE JOB
F1 drivers are one of the highest paid athletes in the world.
A top F1 driver has a very strong and healthy heart.
An F1 driver has muscles as fit as that of body builder.
They get to ride the fastest and most advanced car in the
A rich man’s sport.
Too much carbon emission and fuel consumption.
NEGATIVES OF THE JOB
A Week in the Life of a Formula One Driver
Thursday: The Formula One driver flies into the racetrack and spends some
time with the team, checking that his car is OK and working out strategy for the
Friday: Practice starts very early on Friday morning, especially if the driver's
team has signed up for the extra two-hour test session. The driver usually gets to
the track at about 8 a.m.
Saturday: Saturday is a very important day, because what happens today decides
the grid for Sunday's race. The driver attends two practice sessions in the morning
and then a warm-up before he actually qualifies his car.
An article by Jonathan Noble and Mark Hughes
Sunday: Race day is by far the most important, and busiest, day of the
The day often involves everything from warming up and meeting sponsors to
race day parades and post-race functions.
Monday: After the race day, a driver has to go to the gym for a few hours to
make sure he stays in shape and then fly to tracks to get ready for that week's
Tuesday: Less than 48 hours after the Grand Prix, the Formula One
driver is back in the cockpit, working hard on developments and
improvements for the next race
Wednesday: Another day of testing, although a
driver may be able to fly home this evening to get
ready for the following week's Grand Prix.
“ Finishing races is
important, but racing is
more important. ”
“ And that just shows you
how important the car is in
Formula One Racing.”
