Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt. One Watt is a small amount of power.

## What is the unit of electric power answer?

The SI unit of power is the watt, one joule per second.

## What is the unit of electricity Class 10th?

unit of electric charge is coulomb (C). One coulomb is nearly equal to 6 × 10^{18} electrons. S.I. unit of electric current is ampere (A).

## What is electricity and its SI unit?

Electric power is the rate of doing work or it is the work done in 1 second. The S. I. unit of power is ‘Watt’. If a current of 1 ampere flows through a metallic conductor at a potential difference of 1 volt, the power is said to be 1 watt. or 1 Watt = 1 Volt × 1 Ampere.

## What is current unit?

The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp.

## What is the basic unit of electricity?

The ampere (A) is a basic SI unit of electric current. It can be defined as the amount of electric charge or number of electrons that pass a point in a circuit in one second. One ampere equals 6.241*10^{18} electrons passing a point per second or one coulomb per second. (The coulomb (C) is the SI unit of electric charge.)

## What are the 4 basic units of electricity?

Therefore, the 4 basic units of electricity are volts, amps, ohms, and watts.

## What is electricity Class 9?

Electricity of Class 9

If a charge particles moves then it results as current. Electricity has an important role in modern society. In a span of more than 900 years, electricity convenient and widely used forms of energy in the world.
