Rearrange power equations to calculate energy transferred, work done or time.

To rearrange power equations, we start with the definitions of power: power (P) is the rate at which energy (E) is transferred or work (W) is done over time (t). The equations can be expressed as P = E/t and P = W/t. To find energy transferred, we rearrange to E = P × t. For work done, we rearrange to W = P × t. Conversely, to find time, we can rearrange to t = E/P or t = W/P. Understanding these relationships allows us to calculate any of the three variables when the other two are known.
