Write down the equation which links energy transferred (E), power (P) and time (t)

The equation that links energy transferred (E), power (P), and time (t) is given by:

$E = P \times t$

Explanation

In this equation:

• E represents the energy transferred, typically measured in joules (J).
• P stands for power, which is the rate at which energy is transferred or converted, measured in watts (W). One watt is equivalent to one joule per second.
• t denotes the time over which the power is applied, measured in seconds (s).

This relationship indicates that the total energy transferred is the product of the power and the time during which the power is utilized. For example, if a device operates at a power of 100 watts for a duration of 5 seconds, the energy transferred would be $E = 100 \, \text{W} \times 5 \, \text{s} = 500 \, \text{J}$. Understanding this equation is crucial in various fields including physics and engineering, as it allows for the calculation of energy consumption and efficiency in electrical systems.
