Units used for measurement of electrical quantities voltage, current and power are Volt, Ampere and Watts.
Electric current is the rate of change of charge with respect to time,
The electrical unit used for measuring current is called Ampere,
1 Ampere= 1 coulomb/sec
Current --- Ampere (A)
Voltage is the energy required to move a unit charge through an element. So, the voltage between two terminals is named A, and B is the energy required to move a test charge between these terminals.
and the electrical unit used to measure the voltage is Volt.
Electric power is the rate at which an element absorbs energy with respect to time.
And unit used to measure power is Watt.
And some standard electrical units are mentioned below,
