Q: What is the correct answer for CUET UG Physics Q34?

The correct answer is b. Let's match each item from List-I with its corresponding item in List-II regarding power dissipation in AC circuits: (A) Resistive Circuit: In a purely resistive circuit, voltage and current are in phase, leading to continuous power dissipation. Compared to circuits with reactive components, for a given impedance, the power dissipated is often referred to as 'Maximum power dissipation' in context

Let's match each item from List-I with its corresponding item in List-II regarding power dissipation in AC circuits:
(A) Resistive Circuit: In a purely resistive circuit, voltage and current are in phase, leading to continuous power dissipation. Compared to circuits with reactive components, for a given impedance, the power dissipated is often referred to as 'Maximum power dissipation' in context of non-reactive power. So, (A) matches (IV) Maximum power dissipation.
(B) Purely inductive or capacitive circuit: In ideal inductors and capacitors, the current and voltage are 90 degrees out of phase, meaning the average power dissipated over a full cycle is zero. They store and release energy, but do not dissipate it. So, (B) matches (I) No power dissipation.
(C) LCR series circuit: In a general LCR series circuit, only the resistor dissipates average power. The inductor and capacitor merely exchange energy with the source. So, (C) matches (III) Power dissipated only in resistor.
(D) Power dissipated at resonance in LCR circuit: At resonance (X_L = X_C), the impedance of an LCR series circuit becomes purely resistive (Z=R), and the power factor (cosφ = R/Z) becomes 1. This condition leads to the maximum possible power dissipation for a given applied voltage. So, (D) matches (II) Maximum power dissipation because X_L = X_C.
Combining these, the correct option is (A)-(IV), (B)-(I), (C)-(III), (D)-(II).
