NEET Physics AC Voltage Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Step-up transformer (i) High voltage transmission reduces I²R losses (b) Step-down transformer (ii) Voltage is stepped down for consumer supply (c) AC current in R (iii) Current lags voltage in inductor (d) AC current in C (iv) Current leads voltage in capacitor
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iv, d-iii
a-ii, b-iii, c-i, d-iv
Correct Answer
Detailed Explanation
A step-up transformer increases voltage for efficient long-distance transmission, thereby reducing I²R losses. The step-down transformer lowers the voltage for safe consumer use. The AC current in a resistor is in phase with the voltage, while in an inductor, it lags, and in a capacitor, it leads the voltage.
