JEE Main 2022 — Alternating Current Question with Solution
From: JEE Main 2022 (Online) 28th June Morning Shift
Question
An AC source is connected to an inductance of 100 mH, a capacitance of 100 F and a resistance of 120 as shown in figure. The time in which the resistance having a thermal capacity 2 J/C will get heated by 16C is _____________ s.
This question includes a diagram. The text above accompanies the figure.

Step-by-step explanation
L = 100 103 H
C = 100 106 F
R = 120
L = 10
XC XL = 90
For heat resistance by 16C heat required = 32 J
