Physics-AC Voltage
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) Step-up transformer (i) Reduces transmission losses (b) Phase difference between voltage and current (ii) Current leads voltage (c) Power factor in AC circuit (iii) Ratio of R to Z (d) Inductive reactance (iv) Opposes change in current
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-i, b-iii, c-ii, d-iv
C
a-ii, b-i, c-iv, d-iii
D
a-iv, b-ii, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
A step-up transformer increases voltage to reduce current, thereby minimizing I²R losses in transmission. The phase difference indicates how current and voltage interact, with the power factor defined as the ratio of resistance to impedance, while inductive reactance opposes changes in current.
