Problem 3.124

Find the potential difference \(\varphi_{A}-\varphi_{B}\) between points \(A\) and \(B\) of the circuit shown in Fig. \(3.26 .\)

Reveal Answer
φA−φB=(C2E2−C1E1)/(C1+C2+C3)\varphi_{A}-\varphi_{B}=\left(C_{2} \mathscr{E}_{2}-C_{1} \mathscr{E}_{1}\right) /\left(C_{1}+C_{2}+C_{3}\right)
