Question

In the circuit shown below the resistance are given in ohms and the battery is assumed ideal with emf equal to 3.0 volts. The resistor that dissipates the most power is - 

(A) R₁ 

(B) R₂ 

(C) R₃ 

(D) R₄ 

Answer 1

Correct Option :-(A) R₁

Explanation :-

Power dissipate in R₁ is maximum as its current is maximum and its 

resistance is also 40Ω which is higher than R₅R₄.
