## What is the unit of power?

WattPower/SI units.

## What is the current formula?

Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.

## What is the formula of electric power?

In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules. Electrical power can also be defined as the rate of by which energy is transferred.

## What is the formula of power Class 10?

The electric power is given by P = VI. Where V is the potential difference, I is the electric current and P is the electric power.

## What is work formula?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).

## What is a power in math?

An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor. 31.

## What are the three major units of power?

Some of the common power units include ergs per second (erg/s), foot-pounds per minute, dBm, food calories per hour or kilocalories per hour, horsepower (hp), BTU per hour (BTU/h).

## What is power in simple words?

Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles. An example of power is the authority a local government has to collect taxes. … Power means to supply with energy or force.

## How do you calculate power?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

## What is the power of an equation?

It is the work/time ratio. Mathematically, it is computed using the following equation. The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time.

## What is average power formula?

If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of P=V2/R, where V replaces the rms voltage. An ac voltmeter attached across the terminals of a 45-Hz ac generator reads 7.07 V.
