Electricity

Voltage
Voltage is the potential difference in electrical charge between two different areas in a circuit.Voltage is the force that pushes the current along through the circuit.
Current
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire.
Resistance
The difficulty an electric current faces to pass through an object.Materials can be classified into one of the three following categories
conductors (high)
semiconductors (middle)
- Insulator (low)
Power
In physics power is how much work is done
the formula for power is p= W/t
the formula for power is p= W/t
