Question 487: Current Electricity

Question

The potential difference $\left(V_A-V_B\right)$ between the points A and B in the given part of the circuit

Accepted Answer

Given circuit can also be drawn as,
$$\begin{aligned}
&	ext { By Kirchhoff's voltage law, }\
&\begin{array}{ll} 
& \mathrm{V}_{\mathrm{A}}-(4 	imes 3)-(5)-(2 	imes 3)-\mathrm{V}_{\mathrm{B}}=0 \
	herefore \quad & \mathrm{~V}_{\mathrm{A}}-12-5-6-\mathrm{V}_{\mathrm{B}}=0 \
	herefore \quad & \mathrm{~V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{B}}=+23 \mathrm{~V}
\end{array}
\end{aligned}$$
