Question

A current of 3 amperes flows through the 2 ohm
resistor shown in the circuit. The power dissipated
in the 5ohm resistor is :-

(1) 1 watt
(2) 5 watts
(4) 2 watts
(3) 4 watts​

Answer 1

Explanation:

Given A current of 3 amperes flows through the 2 ohm  resistor shown in the circuit. The power dissipated  in the 5 ohm resistor is  

• Given current across 2 ohm resistor is 3 A
• Potential across 2 ohm resistor V = I R
•                                                         = 3 x 2
•                                                         = 6 V
• In parallel connection potential is equal.
• Current flow in 1 ohm and 5 ohm resistor I = V /  R
•                                                                      = 6 / 5 + 1
•                                                                    6 / 6 = 1 A
• Now dissipation of power in 5 ohm resistor is I^2 R
•                                                                     = 1^2 x 5
•                                                                        = 5 W
