An alarm clock uses 5.0 watts of electric power. If the clock is plugged into 120 volts outlet, what electric current is in the clock's circuit?

Power = P = I*V
I = P/V = 5.0/120 = 0.047 Amperes
Since it almost certainly running on AC, the current computed is the rms average value (root mean square)
