Electric power is the rate at which electrical energy is transferred or consumed by an electrical circuit. It is usually measured in watts (W) and can be calculated using the formula P=VI, where P is the power in watts, V is the voltage in volts, and I is the current in amperes.

Electric power has many practical applications, such as in the generation and distribution of electricity to power homes and businesses, as well as in the design and operation of various electrical devices and machines. Understanding how to calculate and manage electric power is essential for ensuring the safe and efficient operation of electrical systems.

The formula for determining electric power using energy and time is defined as:

\(P\) \(=\) \(\frac{E}{t}\)

\(t\): the duration

\(P\): the electric power

\(E\): the electric energy

The SI unit of electric power is: \(watt\text{ }(W)\)

## Find t
