Physics-Power in AC Circuits
NEET Physics Power in AC Circuits Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) rms voltage | (i) ω L |
| (b) reactance | (ii) cosφ |
| (c) power factor | (iii) V/√2 |
| (d) impedance | (iv) Z |
A
a-iii, b-i, c-ii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iv, b-ii, c-iii, d-i
D
a-i, b-iv, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
The rms voltage is defined as V/√2, reactance can be inductive (ω L), the power factor is given by cosφ, and impedance is represented by Z. These definitions are consistent with the NCERT context regarding power in AC circuits.
