Question

Question 1

An AC circuit has a voltage of 11.0cos(wt) V. There is also a 230. ? resistor and a 3.10 nF capacitor in the circuit. What is the value of V_R and V_C if the emf frequency is 3.90 kHz?

a) V_R = 11.0 V and V_C = 0.192 V

b) V_R = 11.0 V and V_C = 0.103 V

c) V_R = 0.103 V and V_C = 11.0 V

d) V_R = 0.192 V and V_C = 11.0 V

Question 2

You want a resonance frequency of 1.12×10³ Hz and already have a circuit with a 73.0 ? resistor and a 8.30 ?C capacitor. What inductor should be added in series to get the correct frequency?

a) 0.00271 H

b) 0.00215 H

c) 0.117 H

d) 0.00243 H
