The Norton’s equivalent source in amperes as seen into the terminals X and Y is _______.

A non-ideal voltage source V_S has an internal impedance of Z_S. If a purely resistive load is to be chosen that maximizes the power transferred to the load, its value must be

A series RLC circuit is observed at two frequencies. At $$\omega_1$$ = 1k rad / s, we note that source voltage $$V_1=100\angle0^\circ V$$ results in a current $$I_1=0.03\angle31^\circ\;A$$. At $$\omega_2$$ = 2 k rad/s, the source voltage $$V_2=100\angle0^\circ\;V$$ results in a current $$I_2=2\angle0^\circ\;A$$. The closest values for R,L,C out of the following options are

The line A to neutral voltage is $$10\angle15^\circ\;V$$ for a balanced three phase star-connected load with phase sequence ABC. The voltage of line B with respect to line C is given by
