Correct answer: D. D
- A. A
- B. B
- C. C
- D. D
Explanation
The phase diagram for an inductor in an AC circuit typically shows the relationship between voltage (V) and current (I) as a vector diagram. In this diagram: The voltage (V) is represented as a vector along the horizontal axis (real axis).The current (I) is represented as a vector along the vertical axis (imaginary axis).The angle between the voltage vector and the current vector represents the phase difference between them.For an inductor, the voltage vector leads the current vector by 90 degrees. This means the voltage is ahead of the current by 90 degrees in the circuit.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
