The power of a certain CD player operating at 120 V rms is 20.0 W. Assuming that the CD player behaves like a pure resistor, find (a) the maximum instantaneous power; (b) the rms current; (c) the resistance of this player.
In a place where the electrical outlets supply alternating currents with V rms = 22V and I rms = 11A, the frequency of these AC oscillations is f = 23Hz. If at time t=0s, the instantaneous current is zero, after what earliest time in ms will the instantaneous current be maximum?
. A pair of power transmission lines each have a 0.95Ωresistance and carry 740 A over 9.0 km. If the rms inputvoltage is 42 kV, calculate (a) the voltage at the other end,(b) the power input, (c) power loss in the lines, and (d) thepower output.
