Question

Consider the RLC circuit shown in the figure.

For parts a-d, select 'True', 'False' or 'Cannot tell' for the following statements.

a)Energy is dissipated in the resistor but not in either the capacitor or the inductor.

b)The voltage drop across the resistor is the same as the voltage drop across the inductor at all times.

c)The current through the inductor always equals the current charging/discharging the capacitor.

d)The current through the inductor is the same as the current through the resistor at all times.

e) What is the value of the inductance L so that the above circuit carries the largest current? (in H) Using the inductance L found,what is the impedance seen by the voltage source? (in Ohms
Data: R = 2.51?102ohms, f = 1.77?103 Hz, C = 6.10?10-3 F, Vrms = 9.69?101 V

(in H) Using the inductance L found,what is the impedance seen by the voltage source? (in Ohms Data: R = 2.51?10^2ohms, f = 1.77?10^3 Hz, C = 6.10?10^ - 3 F, Vrms = 9.69?10^1 V

Explanation / Answer

a) T

b) F

c) T

d) T

e) R=251 ==>f=1770 Hz==>C=6.1E-3F==>Vrms=96.9 V

At resonance for a series circuit, the impedance is at it's minimum value

because the capacitance and inductance are equal in magnitude, and 180 degrees

out of phase.

1770 Hz=1/(2**L*C))==>L=0.000001325452 H or 1.33 H

Z=R (251 )
