Many things happen in electricity. About whom we must have knowledge.

## What is volt, watt, ampere, unit, HP and how is it calculated?

## What is Ampere?

The unit of electric current is ampere A.

According to Ohm’s law**Current = Voltage / Resistance**

## What is a volt?

EMF means the unit of electric carrying force is volt. If 1 ampere to 1 ampere current is given, then it is called one volt.

**According to Ohm’s lawVoltage = Current × Resistance**

## What is HP?

HP means: Horse Power

**1 British HP = 746 watts1 Metric HP = 735.5 Watt**

## What is watt?

The unit of electric power is watts

**1 watt = 1 joule per second **

**Power = Voltage × Current**

## What is a unit?

The unit of electrical energy is the unit.

**1 Unit = 1 kilowatt per hourOr 1 unit = 1000 watt per hour**
