Question

Consider the RLC circuit shown in the figure. Select True'. 'False' or 'Cannot tell' for the following statements. The current through the inductor is the same as the current through the resistor at all times. Energy is dissipated in the resistor but not in either the capacitor or the inductor. The voltage drop across the resistor is the same as the voltage drop across the inductor at all times. The current through the inductor always equals the current charging/discharging the capacitor. Tries 0/20 What is the value of the inductance L so that the above circuit carries the largest current? Data: R = 2.73 Times 102 Ohm, f = 1.89 Times 103 Hz, C = 6.10 Times 10-3 F, Vrms 7.39 Times 101 V. Tries 0/20 Using the inductance found in the previous problem, what is the impedance seen by the voltage source?

Explanation / Answer

1. True (as same current passes in the loop)
2. True (as perfect inductor and perfect capacitor do not dissipate energy)
3. False (Voltage drop also occurs at capacitor)
4. True (same current in the circuit)
5. For largest current resonance must occur

L= 4**/(f*f*C)= 1.811*10-3 (Ans)

6. impedance seen by source is the Resistance which is 273
