BE.02.06 - RLC Circuits Quiz

A parallel RLC circuit is shown in the diagram. Select one:

• I = V/R

• VL1 V > VC1

• VC1=VL1

• I = V/R + V/L - V/C

Can the neutral branch currents be added directly to obtain the total circuit current IL?

• Yes, you can at high frequencies.

• Yes, because the currents are in phase.

• No, because the currents are out of phase.

• No, because the currents are 180° out of phase.

In this circuit, does the sum of the component voltage drops equal the applied source voltage (VAC)?

• Yes, because all voltage drops are in phase.

• Yes, at very high frequencies.

• No, because the voltage drops are out of phase.

• No, because the voltage drops are 180° out of phase.
