In the circuit shown in the figure, if potential at point A is taken to be zero , the potential at point B is ?

Options:

Answer:

Solution:

Current From D to C = $3 A$

$∴ V_{D} - V_{C} = 2 \times 3 = 6 V$

$V_{A} = 0 ∴ V_{C} = - 1 V$

$∴ V_{D} + 1 = 6$

$\Rightarrow V_{D} = 5 V$

$V_{D} - V_{B} = 2$

$∴ 5 - V_{B} = 2$

$\Rightarrow V_{B} = 3 V$
