Question

The sinusoidal voltage v= 200 sin(2ttfe+60) is plotted in the Figure wheref=897,62 Hz. Find t, in milli-seconds 20 200 te 11 ms. 0 TT 2TT -160° Answer: If the source voltage is E= 24 volts, R=1.1 kOhm, R2=3.8 kOhm and R3-6.5 kOhm. The measured voltage by the voltmeter in the circuit of the figure is Volts w Rk Riko ŽR in

Answer 1
