Question

A 750 Hz ,20 V ( rms ) source is connected to a resistance of 100 , an inductance of 0.1803 H and a capacitance of 10 F all in series. The time in which the resistance (heat capacity 2 J/ ^ C will get heated by 10^ C. (assume no loss of heat to the surroudings) is close to

Accepted Answer

Correct answer: A. (a) JEE Main 2020 H= (I_ rms )^2 Rt mS T= (1_ rms )^2 Rt = mS T (I_ rms )^2R = 2 10 (I_ rms )^2100 I_ rms= 20 (X_L-X_C )^2+R^2 ,X_L=2 750 .1803 X_C= 12 750 10^-6 t come out ≃348s
