NEET Physics AC Voltage Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Inductor behavior | (i) Current leads voltage by π/2 |
| (b) Capacitor behavior | (ii) Current lags voltage by π/2 |
| (c) Average power in AC | (iii) Power factor formula |
| (d) Power factor | (iv) P = I V cosφ |
A
a-ii, b-i, c-iv, d-iii
B
a-i, b-ii, c-iii, d-iv
C
a-ii, b-iv, c-i, d-iii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
In the case of an inductor, the current lags the voltage by π/2, while for a capacitor, the current leads the voltage by π/2. Additionally, the power factor is defined as P = I V cosφ, which relates to average power in AC circuits.
