Power is the rate at which work is done or energy is transferred in an electrical circuit. It can be calculated for both DC and AC circuits and is essential for understanding energy consumption and generation.

High power indicates rapid energy transfer, while low power indicates slower energy usage.

Power is the rate at which work is done or energy is transferred. Work is the energy transferred to or from an object via a force causing displacement. Time is the duration over which the work is done.

In engines, power indicates how quickly the engine can do work, affecting performance and efficiency. Power ratings help in determining energy consumption and efficiency of appliances. In thermal systems, power calculations are essential for designing heating and cooling systems.

Power, P_{(W)} in watts is calculated by dividing the total change in work, dW_{(J)} in joules by change in time, dT_{(s)} in seconds.

Enter the values of total change in work, dW_{(J)} and change in time, dT_{(s)} to determine the value of Power, P_{(W)}.

Power, P_{(W)} = dW_{(J)} / dT_{(s)}

P_{(W)} = power in watts, W.

dW_{(J)} = change in work in joules, J.

dT_{(s)} = change in time in seconds, s.

**Calculate the power if 150 joules of work is done in 5 seconds.**

Given: dW_{(J)} = 150J, dT_{(s)} = 5s.

Power, P_{(W)} = dW_{(J)} / dT_{(s)}

P_{(W)} = 150 / 5

P_{(W)} = 30W.

**Determine the work done if a power of 60 watts is applied for 10 seconds.**

Given: P_{(W)} = 60W, dT_{(s)} = 10s.

Power, P_{(W)} = dW_{(J)} / dT_{(s)}

dW_{(J)} = P_{(W)} * dT_{(s)}

dW_{(J)} = 60 * 10

dW_{(J)} = 600J.
