Question

Three identical resistors $R_{1}=R_{2}=R_{3}$ are connected as shown to a battery of constant e.m.f. The power dissipated is

• A. The least in $R_{1}$
• B. Greatest in $R_{1}$
• C. In the ratio $1: 2$ in resistance $R_{1}$ and $R_{2}$ respectively
• D. The same in $R_{1}$ and in the parallel combination of $R_{2}$ and $R_{3}$

Answer 1

Answer: (B)

Power dissipated is maximum in $R_{1}$.
