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 -

Options

  1. AR ₁
  2. BR ₂
  3. CR ₃
  4. DR ₄

Correct answer

A. R ₁

Step-by-step solution

Power dissipate in R ₁ is maximum as its current is maximum and its resistance is also 40 which is higher than R ₅ R ₄ .
