Question:

Match List - I with List - II.

List - I

List – II

 (A) 

 Resistive circuit

 (I)

 No power dissipation

 (B)

 Purely capacitive or inductive circuit 

 (II)

 Maximum power dissipation as XL = XC 

 (C)

 Series L-C-R circuit

 (III) 

 Power dissipated only in the resistor

 (D)

 Series L-C-R circuit at resonance

 (IV)

 Maximum power dissipation

Choose the correct answer from the options given below:

Options:

(A)-(IV), (B)-(I), (C)-(III), (D)-(II)

(A)-(I), (B)-(II), (C)-(IV), (D)-(III)

(A)-(IV), (B)-(II), (C)-(I), (D)-(III)

(A)-(I), (B)-(IV), (C)-(III), (D)-(II)

Correct Answer:

(A)-(IV), (B)-(I), (C)-(III), (D)-(II)

Explanation:

Maximum power is dissipated in resistive circuit.

Power can be lost only when there is a resistance in the circuit. In Purely capacitive or inductive circuit Power loss is zero.

In Series L-C-R circuit Power dissipated only in the resistor

Series L-C-R circuit at resonance Maximum power dissipation as XL = XC .
