Electric power is the rate at which work is done or energy is transformed into an electrical circuit. Electric power is measured in watts. Learn its definition, formula, unit along with solved examples at BYJU'S.
This formula is to be used for calculating power when voltage V and resistance R are known to us. It is clear from equation (3) that power is inversely proportional to the resistance. Thus, the resistance of high power devices is smaller than the low power ones. For example, the resistan...

Convert the work from kilojoules to joules by multiplying by 1000 before applying the formula. How does time affect power?Power is inversely proportional to time for a constant amount of work; the less time it takes to do work, the greater the power. Is it possible for a machine to have...
Standard units of nuclear energy aremegaelectronvolts (MeV). In nuclear and particle physics, theenergetics of nuclear reactionsare determined by the reaction’s Q-value. TheQ-valueof the reaction is defined as thedifferencebetween the sum of themassesof theinitial reactantsand the sum of the...
Not everyone is an expert in physics. But with regards to the concept of energy consumption, it should be something of common sense. As a matter of fact, knowledge of energy use is a great initial step in making the necessary changes to your electricity bill and optimizing your energy consu...
