The equilvalent resistance and potential difference between AA and BB for the circuit respectively are The equilvalent resistance and potential difference between A and B for the circuit respectively are

Options

  1. A4Ω,8 V4 \Omega, 8 \mathrm{~V}
  2. B8Ω,4 V8 \Omega, 4 \mathrm{~V}
  3. C2Ω,2 V2 \Omega, 2 \mathrm{~V}
  4. D16Ω,8 V16 \Omega, 8 \mathrm{~V}

Correct answer

A. 4Ω,8 V4 \Omega, 8 \mathrm{~V}

Step-by-step solution

The equivalent resistance between AandBA and B is 1R′=16+16+13=23\frac{1}{R^{\prime}}=\frac{1}{6}+\frac{1}{6}+\frac{1}{3}=\frac{2}{3} or R′=32=1.5Ω\quad R^{\prime}=\frac{3}{2}=1.5 \Omega Now the equivalent resistance between AandBA and B is R′′=1.5+2.5=4ΩR^{\prime \prime}=1.5+2.5=4 \Omega Now by Ohm's law, potential difference between AandBA and B is given by VA−VB=iR=2×4.0=8volt\begin{aligned} V_A-V_B & =i R=2 \times 4.0 \\ & =8 \mathrm{volt}\end{aligned}
