Question

Figure P22.1 shows the AC voltage produced by a particular source. Estimate (a) the frequency of this voltage, (b) the amplitude of this voltage, and (c) the rms value of this voltage. (d) If this AC voltage were attached to a lightbulb, would you notice the flicker of the bulb?

Explanation / Answer

a)F=1/T=1/0.004=250Hz

b)Amplitude=4V

c)Vrms=4/sqrt(2)=2sqrt(2)=2.83V

d)No, Since the frequnecy is very high.
