Calculate the following.
a) What is the magnitude of the voltage in a wall socket if the effective voltage is 240 Vrms?
b) What is the magnitude of the current if the effective current is 360 mArms?
c) If a voltage source has a time-domain value of 45 V cos (100 rad/s * t - 80°), what is the effective voltage in Vrms?
d) If a current source has a time-domain value of 120 A cos (2(pi) 300 krad/s * t + 90°),what is the effective current in Arms?
