Problem 2 The voltage source in the circuit shown below is generating the triangular waveform shown in (i) below. Assume the energy stored in the capacitor is zero at t=0. (a) Derive the numerical expressions for v o (t) when v o (t)=0 for the time intervals: t<0; 0 t 5 µ s; 5 µ s t 15 µ s; and15 µ s t 20 µ s. (b) Sketch the output waveform between 0 and 20 µ seconds. (c) If the triangular input voltage continues to repeat itself for t>20 µ s, what would you expect the output voltage to be? Explain your answer. (i) (ii)

Unformatted text preview: home is 120 volts. What is the maximum (peak) value of the voltage at this outlet? (b) Find the rms value of the half-wave rectified sinusoidal voltage shown below. Problem 4 Basic Electrical Phasors A 40 kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 2.5mV. When this voltage is applied across the terminals of a capacitor, the resulting steady-state current has a maximum amplitude of 125.67 µ A. (a) What is the frequency of the capacitor current in radians per second?(b) What is the phase angle of the current? (c) What is the capacitive reactance of the capacitor? (d) What is the capacitance of the inductor in microfarads? (e) What is the impedance of the capacitor?
