MathLivePower as rate of energy transfer
Power is the instantaneous rate at which energy is transferred, used, or transformed, found as the time derivative of energy. It applies whenever the rate of energy flow in a system must be quantified.
P = \frac{\mathrm{d} E}{\mathrm{d} t}What the symbols mean
| power, in watts (\mathrm{W}) | |
| energy, in joules (\mathrm{J}) | |
| time, in seconds (\mathrm{s}) |
