University of Saskatchewan Department of Electrical Engineering EE 212 Assignment #1 Instructor: R. Gander _____________________________________________________________________________ 1. A sinusoidal voltage v(t) with 10-volts peak amplitude and 60-Hz frequency is applied to the circuit shown in Figure 1. The currents i 1 (t) and i 2 (t) through the elements 1 and 2 of the circuit are given. Figure 1 v(t) = Vm sin ωt, where Vm is the peak of the sinusoid and ω is the angular frequency. i 1 (t) = 10 sin ωt A i 2 (t) = 10 sin (ωt + 90 0 ) A i. Plot the voltage and current waveforms (on the same graph) for the two circuit elements in Figure 1. ii. Determine the time period, angular frequency, peak and RMS values of the current i 2 (t). iii. Determine the instantaneous currents in the two circuit elements when the instantaneous voltage is 10 volts. iv. Calculate the total current i(t) drawn from the source using a Phasor Diagram.
