Question 388: Electrostats & Capacitance

Question

For the given circuit, in the steady state, $\left|\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{D}}\right|=$
________ V.

Accepted Answer

In steady state, capacitor behaves as an open circuit. Circuit is :
$\Rightarrow i_{A B}=\frac{6}{3}=2 \mathrm{~A} $
$ i_{A D}=\frac{6}{12}=0.5 \mathrm{~A}$
$\Rightarrow V_{B}+2 	imes 2-10 	imes 0.5=V_{D}$
$\Rightarrow V_{B}-V_{D}=1$ volt
