What is Power?
Power is the rate of doing work or the rate of transfer of energy. It is denoted by P. In other the the ratio of the work done by the object by the time taken is defined as the power of the object.
P = W/t
- SI unit is Watt (Js−1).
- Commercial unit of power is kWh, i.e., energy used in 1 hour at 1000 Joules/second.
1kWh = 3.6×106 J
Energy
Energy in Physics is defined as the capacity of a body to do work. It is the capacity to complete a work. Energy can be broadly categorized into two categories, Kinetic Energy and Potential Energy. The capacity of an object to do the work is called the Energy. In this article, we will learn about, Energy, Types, of Energy, the Law of conservation of Energy, and others in detail.
Before learning about energy, we must first learn about, Work Done, so let’s start with the same.
