Question

In the given circuit the potential at point B is zero, the potential at points A and D will be

• A. $v_{d} \propto E$
• B. $v_{d} \propto E^{2}$
• C. $v_{d} \propto \sqrt{E}$
• D. $v_{d} \propto \frac{1}{E}$

Answer 1

Answer: (D)

$v_{d} \propto \frac{1}{E}$

Answer 2

: $V_{A} - V_{B} = 2 \times 2 = 4V$

$\therefore V_{A} - 0 = 4V \Rightarrow V_{A} = 4V$

According to question$V_{B} = 0$

Point D is connected to positive terminal of battery of emf 3 V.
