Write the expression for Millman’s equivalent source of n number of parallel connected voltage sources.
Step-by-Step
\overline{{{Z}}}_{\mathrm{eq}}=\left(\frac{\overline{E_1}}{Z_1}+\frac{\overline{E_2}}{Z_2}+\frac{\overline{E_3}}{Z_3}+…+\frac{\overline{E_n}}{Z_n}\right)\overline{Z_{\text{eq}}}
\overline{Z} _{\mathrm{eq}}=\frac{1}{{\frac{{1}}{\mathrm{\overline{Z} }_{1}}}+{\frac{\mathrm{ 1}}{\mathrm{\overline{Z} }_{2}}}+\frac{{{{{{1}}}}}}{\overline{Z} _3} +\ldots+{\frac{\ 1}{\mathrm{\overline{Z} }_{n}}}}
where, \overline{E}_{1}, \overline{E}_{2}, \overline{E}_{3}…= Emf of voltage sources in parallel.
\overline{Z_{1}}, \overline{Z_{2}}, \overline{Z_{3}}… = Internal impedance of voltage sources.
