Relationship between Energy And Power
Energy and power are closely related concepts. Each measures different aspects of work and how it interacts with time. Energy is the capacity to do work, while Power is the rate at which this work is done or energy is transferred.
The relationship between energy and power is given by the following formula:
P = E/t
where:
- P is power, measured in watts (W),
- E is energy, measured in joules (J),
- t is time, measured in seconds (s).
This formula implies that power is the amount of energy consumed per unit of time. For example, if a device uses 100 joules of energy in 10 seconds, its power consumption would be:
P = 100 J/ 10 s = 10 watts
We can also determine the amount of energy used if we know the power and the time duration:
E = P × t
For instance, if a light bulb has a power rating of 60 watts and it is on for one hour (3600 seconds), the energy used would be:
E = 60 W × 3600 s = 216,000 joules

Difference between Energy and Power
Energy is the ability to do work, while power is the rate at which work is done. While energy is measured in joules, power is measured in watts. Energy exists in various forms, such as kinetic, potential, and thermal. Power determines how quickly work is done, impacting everyday devices. In this article, we are going to learn about the differences between Energy And Power in detail.
