INTRODUCTION

Voltage:

The difference in potential energy of the charges is called potential difference. Potential difference is also known as voltage and it is denoted as V, unit is Volts (V).

Voltage is also expressed in terms of energy per unit charge.

Current:

It is defined as the rate of flow of electrons in a conductive or semi conductive material. It is denoted by I, unit is Ampere (A).


Power:

Power is defined as rate of change of energy and is denoted by P, unit is Watts (W)



Multiply and divide by dq


Energy:

Energy is the capacity for doing work.

It is the stored work, unit is Joules (J)
