Best ResponseYou've already chosen the best response.0W = A x V.... so 4320?

Best ResponseYou've already chosen the best response.0Power is the rate of change of work. The amount of work moving a charge C over a potential difference V is W = VC Now the rate of change of work where V is constant is \[ Power = P = V \frac{\Delta C}{\Delta t} = V I \] where \( I \) is current. By definition current is the rate at which charge moves. Hence to find the power of this circuit, calculate \[ P = VI \]

Best ResponseYou've already chosen the best response.0or convert to watts?!?

Best ResponseYou've already chosen the best response.0Watt = Joule/sec hence it must be that VC has units Joules. Its a good exercise to understand why that is the case.
