What is the formula of SI unit of power?
The SI unit of electric power is the watt (W). The rate at which electric energy is dissipated or consumed in an electric circuit is termed as electric power. The power P is given by, P = VI. The SI unit of electric power is the watt (W).
What are the units for power in physics?
WattPower / SI unitThe watt is a unit of power or radiant flux. In the International System of Units, it is defined as a derived unit of 1 kg⋅m²⋅s⁻³ or, equivalently, 1 joule per second. It is used to quantify the rate of energy transfer. The watt is named after James Watt, an 18th-century Scottish inventor. Wikipedia
What is power describe the formula of power?
P = E/t: This formula is also called the mechanical power equation. Here E stands for energy in joule and t stands for time in seconds. This formula states that the consumption of energy per unit of time is called power.
Why the SI unit of power is watt?
The SI unit of power is Watt. The watt is named after James Watt. Power is the amount of energy transferred per unit time. 1 watt (W) = 1.00 joules per second (J/sec).
How do you calculate the power of a power?
When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.
What is the formula for 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 power write the SI unit of power Class 9?
Power is defined as rate of doing work. It is also defined as rate at which energy is consumed. SI unit of power is watt.
What is unit power?

What is the SI unit of power?
The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
How do you calculate power in physics?
Useful energy is the energy that can be used to do a certain work.
What are the SI units for Physics?
