4. ELECTRICAL
CIRCUIT
A closed path through which electrons
travel to create electric currents is
known as an electric circuit.
It is a relatively straightforward idea
that combines three distinct
elements: an electrical energy source,
a gadget, and a closed loop of
conducting material.

5. • A circuit is a complete path
for the electrons to follow as
they flow, if the path is not
complete, there can be no
flow between two points.
• It would be like a road from your home to
the store, with a bridge out and no
alternative route. There must be a way to
get around the broken bridge if you want to
get where you are going.

6. • Sometimes a circuit is complete
but there is a problem of the
current flowing too fast. This is
called short circuit.
• Short circuit – a circuit which
contains little or no resistance
• The components get too hot due
to the excess current and not
enough resistance to slow it down
and can cause fires

7. Current electricity is the flow of electrical
charge though materials. Every complete
circuit must have a power supply. The power
supply could be the mains, or it could be a
battery.
For a circuit to be complete, there must be
wires connected to both the positive and
negative ends of the power supply.
Electricity can only flow around a complete
circuit that has no gaps.

8. COMPLETE &
INCOMPLETE
CIRCUITS

9. COMPLETE
CIRCUIT
1. There is a power supply (the
battery).
2. There are no gaps anywhere,
so the electrical current can flow
around the entire circuit.
3. The wires connect to both the
positive and negative ends of the
battery.

10. INCOMPLETE
CIRCUIT
1. There is a gap in the
circuit, so the electrical
current cannot flow around
it.
2. The wires do not connect
to the positive and negative
ends of the power supply
(the battery).

15. 2 TYPES OF
ELECTRICAL
CIRCUITS

16. SERIES CIRCUIT

17. Series Circuit - Series circuits are made up of
a number of components that are connected
to one after another in a single continuous
loop. In simple terms, these devices have their
own respective voltages across them and
share similar current flows through series
circuits. If any one of the devices in a series
circuit is broken, the whole circuit fails.

18. PARALLEL CIRCUIT

19. Parallel Circuit – In parallel circuits, different
devices are placed properly and the single
source provides voltage and have a separate
loop of wire. Every device in the circuit has
nearly the same voltage, however, various
devices will typically experience varying
currents. In this parallel circuit, if one of the
devices is broken, the other devices will
continuously function.
