There are two seperate electric circuits: the first circuit contains a sinusoidal AC voltage source of a particular frequency, a resistor and an inductor; the second circuit contains the same sinusoidal AC voltage source, a resistor and a capacitor. Initially, the resistor, inductor, and capacitor have a specific set of parameters that result in the same magnitude of AC currents flowing in both circuits.

Question: if the frequency of the AC voltage sources is increased, which of the following description best describes the circuit behavior?

Question $1$Answer

a$.$

The current magnitude of the first circuit will increase whereas the current magnitude of the second circuit will decrease.

b$.$

The current magnitudes in both circuits will remain the same as their magnitudes do not depend on the frequency.

c$.$

The current magnitude of the first circuit will decrease whereas the current magnitude of the second circuit will increase.

d$.$

The current magnitudes in the two circuits will both decrease because of the Principle of Conversation of Energy.
