Three resistance of 15 Ω each are connected in delta. The resistance of equivalent star will have a value of

In a parallel resonant circuit, the circuit current at resonance is maximum.

An RLC series circuit is under damped. To make it over damped, the value of R

The terms RMS and average values apply only to sine waves.

The synthesis of minimum function was suggested by

A current is flowing through a conductor with non-uniform area of cross-section. Then
