2. An electric circuit is formed with electrons which flow from a
certain voltage source like photovoltaic module, batter by means of
conductor like wire and load them back to the resource.
Circuit technically defines a process of full circle, where the light is
plowed on the electrons gets discharged from the battery and they
further reach the bulb. Thus light is produced with the battery backup
and makes the circuit complete.
If you have a misconception that the process is done when the
electrons gets through the bulb, it is incorrect. This doesn’t makes the
process complete, since the electrons doesn’t flow from its place of
origin. The electric circuit serves as a passageway to the electric
current.
ELECTRIC CIRCUIT

3. They are defined as the best conductors that flows current from end
to end without a mess.
To give complete safety to the electric current passage, the electric
circuit is projected. Designed with a simple formula including a
wire, bulb and a battery, the mechanism is easy and simple to execute.
These are the most fundamental components which are required in
completing the complete process of the circuit.

4. Electric Circuit
Electric circuit can be categorized into two different
types, one is the closed circuit and the other one is the
open circuit.
Closed circuit facilitates continuous current flow.
Whereas in the open electric circuit the passage of
current remains non-continuous.

5. The electric circuit is designed as a closed loop
organized with wires, load, switch, power source
and fuse.
The circuit become complete, when the
current streams out from the –ve terminal
crossing the wire and reaching the +ve terminal
while turning on the switch.
Any mechanism which depletes energy flow by
means of a circuit and convinces it to work is
defined as load.
One of the best examples will be the light
bulb. Yes it consumes electricity through a
circuit and further reflects it as a work source
called light and heat.

6. Types Of Electric Circuit
Electric circuit is categorized into three forms:
1. Parallel Circuit
2. Series Circuit
3. Series Parallel Circuit

7. When considering the parallel circuit, it is designed with multiple
passage way, where the device will execute when any one of the path is
under breakdown.
Being a multi path design, one path will remain broken, but the
other paths will function well creating no hassles

8. SERIES CIRCUIT
When examining the series circuit, it has one way and allows the
electrical current to flow.
In case of electric circuit breakdown, none of the device will
operate.

9. Series Parallel Circuit
When considering the series parallel circuit, quite several
loads are connected to the series whereas the other loads
are connected to the parallel circuits.
In this case, when the series circuit results with
breakdown, the overall functionality of the circuit will be
stopped. Similarly, when the parallel circuit results with any
breakdown, the overall functionality of the parallel circuit
will be stopped.

10. Resistor
 A component that is designed to introduce a
particular resistance into a circuit is called a
resistor.

11. Variable Resistor
• A variable resistor can
made in which a contact
moves along the surface
of a resistance wire and
brings different wire into
the circuit.
• This device is sometimes
called rheostat.

12.  When the contact is placed on the far left the current passes
through only a few coils of the wire.
 As the contact is moved to the right the current flows
through more of the wire and encounters greater resistance.
 When the contact is moved from the right to the left the
current flows through fewer coils of the wire and encounters
less resistance.

13.  A buzzer is an electrical device in which one part
vibrates strongly when a current of electricity passes
through it.
 The vibration produce sound.
