2. z ELECTRICAL CIRCUITS
The electric circuits are closed-loop or path which forms
a network of electrical components, where electrons are
able to flow. This path is made using electrical wires
and is powered by a source, like a battery. The start of
the point from where the electrons start flowing is called
the source whereas the point where electrons leave the
electrical circuit is called the return

SIMPLE CIRCUIT
•Cell: It is the power source.
•Load: It is also termed as the resistor. It is a light bulb that lights when
the circuit is turned on.
•Conductors: They are made of copper wires with no insulation. One
end of the wire is connected the load to the power source and the other
end of the wire connects the power source back to the load
•Switch: It is a small gap in the circuit. There are various types of
switches. A switch can be used to open or close a circuit.

What is an electric current?
An electric current is a flow of microscopic particles called
electrons flowing through wires and components. current
flow from the Negative terminal to the Positive terminal of a
cell.
simple circuits
Here is a simple electric circuit. It has a cell, a lamp and a
switch. cell wires switch lamp To make the circuit, these
components are connected together with metal connecting
wires.
When the switch is closed, the lamp lights up. This is
because there is a continuous path of metal for the electric
current to flow around. If there were any breaks in the circuit,
the current could not flow.

SIMPLE CIRCUIT

6. z SIMPLE LIGHT CIRCUIT
A simple electrical circuit consists of a power source, two
conducting wires (one end of each being attached to each terminal
of the cell), and a small lamp to which the free ends of the wires
leading from the cell are attached.
SIMPLE FAN CIRCUIT
A simple electrical fan circuit consists of a power source,
two conducting wires (one end of each being attached to
each terminal of the cell), and a fan to which the free ends
of the wires leading from the cell are attached

7. z TYPES OF CIRCUIT
There are two types of electrical circuits
1. SERIES CIRCUITS
2. PARALLEL CIRCUITS
SERIES CIRCUITS
The components are connected end-to-end, one after the
other. They make a simple loop for the current to flow
round If one bulb ‘blows’ it breaks the whole circuit and all
the bulbs go out.
PARALLEL CIRCUITS
The components are connected side by side. The current
has a choice of routes. If one bulb ‘blows’ there is still be a
complete circuit to the other bulb so it stays alight.

Where we use series or parallel circuit
In a series circuit,
• every device must function for the circuit to be complete. If
one bulb burns out in a series circuit, the entire circuit is
broken. In parallel circuits, each light bulb has its
own circuit, so all but one light could be burned out, and the
last one will still function.
• All mains operated appliances have switches that are
connected to the live wire (the wire that carries current into
the appliance). When a switch is in series with a device, it
controls the device, allowing us to switch it on and off.
• For example, often lawnmowers have two switches in series
with each other so that both switches need to be pressed
before the mower will turn on.

Advantages of Series Connection
•Less size of wire cable is required in series wiring.
•We use to protect the circuit to connect fuse & circuit breakers in series
with other appliances.
•Series circuit don’t get overhead easily due to high resistance when more
load added in the circuit.
•The lifespan of battery in series circuit is more as compared to parallel.
•It is most simple method of electrical wiring and fault can be easily detect
and repair as compared to parallel or series-parallel wiring.

11. z
Parallel circuit:-
connection is very common in use. Various lamps and electrical
appliances in our homes are connected in parallel so that each
of the lamps or bobs and appliances can be operated
independently. For us to have control over the individual lamps or
loads, they have to be wired in parallel.
Advantages of Parallel Circuit
•Each connected electrical device and appliance are independent from others. This way, switching
ON / OFF a device won’t affect the other appliances and their operation.
•In case of break in the cable or removal of any lamp will not break the all circuits and connected
loads, in other words, other lights/lamps and electrical appliances will still work smoothly.
•If more lamps are added in the parallel lighting circuits, they will not be reduced in brightness (as it
happens only in series lightning circuits). Because voltage is same at each point in a parallel
circuit. In short, they get the same voltage as the source voltage.
•It is possible to add more light fixture and load points in parallel circuits according to future need
as far as the circuit is not overloaded.
•Adding additional devices and components wont increase the resistance but will decrease the
overall resistance of the circuit especially when high current rating devices are used such as air
conditioner and electric heaters.
•parallel wiring is more reliable, safe and simple to use.

Loop in system
A loop system, as the name implies, loops through the service
area and returns to the original point. The loop is usually tied into
an alternate power source. By placing switches in strategic
locations, the utility can supply power to the customer from either
direction.

13. zThe loop system provides better continuity of service than the radial
system, with only short interruptions for switching. In the event of
power failures due to faults on the line, the utility has only to find the
fault and switch around it to restore service. The fault itself can then
be repaired with a minimum of customer interruptions.
The loop system is more expensive than the radial because more
switches and conductors are required, but the resultant improved
system reliability is often worth the price.

14. z
JOINT BOX SYSTEM
An electrical junction box (also known as a ‘jbox’)
is an enclosure housing electrical
connections.[1] Junction boxes protect the electrical
connections from the weather, as well as prevent
people from accidental electric shocks.
