An AC voltage source is connected to a resistor R = 1.45 x 10^2 ohm. The output from an AC voltage source is given by the expression V = (2.80 x 10^2 V) sin2pift. (a) What is the rms voltage across the resistor? V (b) What is the rms current flowing through the resistor?

a)  rms voltage across the resistor = ( 2.8*10^2)/sqrt(2) = 197.98 V

b)  rms current flowing through the resistor = 197.98 / (1.45*100) = 1.365 A
