Electricity affects our lives through electric circuits, which require a closed loop path containing a power source, load, and connectors for electric current to flow. A basic electric circuit consists of a battery, wires, a light bulb, and may include a switch to turn the current on and off, allowing electricity to power devices and light bulbs. For current to flow, a circuit must be closed and continuous without any gaps, whereas an open circuit will not allow current to pass through due to breaks in the loop.
2. Electric current
It is the flow of electric charges
{ To make an electric current, you need a path that
carry it, the path through which the electric current
flow is called: A circuit}
3. The electric circuit
- A circuit should consist of:
Power source Load Connector
Battery Lamp Wires
5. N.B:
- Some circuits have switches that turn the current
electricity on & off.
- The flow of electric charges through a circuit is
called: Current electricity
6. Closed circuit
It is a circuit which doesn’t have any gaps; a
complete, unbroken circuit.
7. Open circuit
A circuit with gaps is called: Open circuit &
current will not flow through it.
