Question

Three identical resistors R1=R2=R3 are connected as shown to a battery of constant e.m.f. The power dissipated is (A) The least in R1 (B) Greatest in R1 (C) In the ratio 1: 2 in resistance R1 and R2 respectively (D) The same in R1 and in the parallel combination of R2 and R3

Tardigrade Admin · Accepted Answer

Power dissipated is maximum in R1.

Q. 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

The least in $R_{1}$

Greatest in $R_{1}$

In the ratio $1 : 2$ in resistance $R_{1}$ and $R_{2}$ respectively

The same in $R_{1}$ and in the parallel combination of $R_{2}$ and $R_{3}$

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

Q. Three identical resistors R1​=R2​=R3​ are connected as shown to a battery of constant e.m.f. The power dissipated is

The least in R1​

Greatest in R1​

In the ratio 1:2 in resistance R1​ and R2​ respectively

The same in R1​ and in the parallel combination of R2​ and R3​
