1. (a) What is the emf frequency f? (b) What is the value of the resistance R? (c) Draw the resistor's voltage and current phasors at t = 15 ms. UR iR Rvc 10 V- ic 0 0.00 s -10 V- C Voltage Current 2. A parallel RC circuit is shown in the figure. Assume an alternating applied emf & = &o cos wt. 0.02 s 0.50 A -0 0.04 s --0.50 A (a) At any instant in time, how are &, UR, and vc related? (b) At any instant in time, how are the emf current i, the resistor current in, and capacitor current ic related? (c) Draw a clearly labeled phasor diagram. Your diagram should include a phasor for &, iR, and ic. Hint: Think carefully about parts (a) and (b) and start from what the resistor and capacitor have in common. (d) Complete the phasor analysis by finding an expression for the peak emf current I.
