Question number: 975
Read the passage given below and answer the questions that follow:
A student constructs a series RLC circuit. While operating the circuit at a frequency f she uses an AC voltmeter and measures the potential difference across each device as (∆V R) = 8.8 V, (∆V L) = 2.6V and (∆V C) = 7.4V.
Question number: 976 (1 of 3 Based on Passage) Show Passage
The circuit is constructed so that the inductor is next to the capacitor. What result should the student expect for a measurement of the combined potential difference (∆V L + ∆V C) across the inductor and capacitor?

Question number: 978 (3 of 3 Based on Passage) Show Passage
What will happen to the value of ( ∆V L) if the frequency is adjusted to increase the current through the circuit?
(∆V L) will remain the same regardless of any changes to f.
There is not enough information to answer the question.
(∆V L) will increase.
(∆V L) will decrease.
