Question

The figure above shows the current i and driving emf for a series RLC circuit. Relative to the emf curve, in which direction does the current curve shift, and does its amplitude increase or decrease in the following situations? (Select all that apply.)

L = inductor

C = capacitor

omega(d) = angular frequency

shifts leftward if we slightly increase L

shifts rightward if we slightly increase L

amplitude increases if we slightly increase L
amplitude decreases if we slightly increase L

shifts leftward if we slightly increase C

shifts rightward if we slightly increase C

amplitude increases if we slightly increase C

amplitude decreases if we slightly increase C

shifts leftward if we slightly increase omega(d)

shifts rightward if we slightly increase omega(d)

amplitude increases if we slightly increase omega(d)

amplitude decreases if we slightly increase omega(d)

Explanation / Answer

shifts leftward if we slightly increase L amplitude decreases if we slightly increase L shifts leftward if we slightly increase C amplitude decreases if we slightly increase C shifts leftward if we slightly increase omega(d) amplitude decreases if we slightly increase omega(d)
