a) If v(t) = 200 sin(160t), how long in seconds does it take to complete 2 cycles? What is the frequency in Hz?. b) For the following waveforms, find the phase shift and indicate which one is leading and which one is lagging: v(t) = 10 sin(wt +5) i(t) = 2 sin(wt + 25) Phase shift: , leading: lagging: c) Express the following in phasor form: 100 sin(330t+ 10): 160sin(330t-60):
