Question

Four resistor are connected as shown in the following figure. A 6V battery of negligible resistance is connected across terminals A and C. The potential difference across terminals B and D will be –

• A. 0 volt
• B. 1.5 volt
• C. 2 volt
• D. 3 volt

Answer 1

Answer: (A)

0 volt

Answer 2

i_i = $\frac{6}{20} = \frac{3}{10}$, i₂ = $\frac{6}{40} = \frac{3}{20}$

V_B –15$\left( \frac{3}{10} \right) + 30\left( \frac{3}{20} \right)$– V_D = 0

V_B – V_D = 0
