Define power, average power, instantaneous power. |
|
Answer» Solution :Power: Power is defined as the RATE of work done or energy delivered. Power (P) = `("Work done (W)")/("TIME taken (t)")` `P=(W)/(t)` Average power: The average power `(P_(av))` is defined as the ratio of the total work done to the total time taken. `P_(av)=("Total work done")/("Total time taken")` INSTANTANEOUS power: The instantaneous power `(P_("inst"))` is defined as the power delivered at an instant (as time interval APPROACHES zero). `P_("inst")=(dW)/(DT)` |
