Question

The frequency of AC supply is determined by the:

• A. Inductive reactance
• B. Capacitive reactance
• C. Resistive reactance
• D. Both inductive and capacitive reactance

Hint:

Inductive and capacitive reactances both depend on the frequency of the AC supply and affect the impedance of the circuit.

Answer 1

The Correct Option is D

Step 1: Frequency dependence. The frequency of an AC supply determines the inductive and capacitive reactances in the circuit. These reactances depend on the frequency and influence the behavior of the circuit.
Step 2: Conclusion. Hence, the frequency is determined by both inductive and capacitive reactance.
