Hope it helps..

Answer 2

1. The flow of electric charge is called electric current.

• "Current = Electric charge/ Time"

• I = Q / t, where 'I' is the electric current in Ampere,

                         'Q' is the electric charge in Coulomb,

                          't' is time in seconds

2. Resistor controls the flow of electricity from a source.

• It ensures that the device receives the current it requires to work.
• It keeps the excess flow of current in check so that the device does not get damaged.

3. Electric bulb is a device that uses electricity from the source.

• It functions only when electric current flows through it.

4. Direct current is the one-way flow of current through the circuit.

• This one-way flow of current is achieved using a diode.
• The direction of flow can be changed by forward and reverse biasing the diode.

5. Hotwires are metal conductors that carry electricity from the source to the load.

• These wires can carry both low voltage and high currents.
• They always have current passing through it when plugged in so they are dangerous to handle.
