Question
The power of a certain CD player operating at 120V rms is 18.0W . Assuming that the CD player behaves like a pure resistance, find the resistance of the player (800 omhs), the rms current (.15A) and the maximum instantaneous power: ? I cant find pmax, got the other two, thanks The power of a certain CD player operating at 120V rms is 18.0W . Assuming that the CD player behaves like a pure resistance, find the resistance of the player (800 omhs), the rms current (.15A) and the maximum instantaneous power: ? I cant find pmax, got the other two, thanksExplanation / Answer
pmax = vrms * Irms
therefire
pmax=120*.15= 18 W
