# What is the commercial unit of electrical energy represent in terms of Joule?

Contents

Express it in joules. The commercial unit of electric energy is kilowatt-hour (kWh). One kilowatt hour is defined as the electric energy consumed by an appliance of power 1000 watt in one hour. The electrical energy used in households, industries and commercial establishments is expressed in kilowatt hour.

## What is the commercial unit of electrical energy and how it is related to joule?

Kilowatt – hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy is used at the rate of 1 watt.

## What is the other name of commercial unit?

Kilowatt-hour is the commercial unit of electrical energy. The other name used for it is units. Here J represents Joules and h represents hour and s represents seconds.

## What is relation between current and power *?

Electric current (Ampere) is affected by the amount of power (wattage) and voltage (volts) used, and the relationship is as follows: The Greater Power (Watt), then the greater Current (Ampere) The Greater Voltage (Volt), then the smaller Current (Ampere) The smaller power (Watt), then the smaller Current (Amperes)

## What do you mean by 1 Joule work?

Joule is the SI unit of work. 1 Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied.

## What is the relation between 1 unit and Joule?
