EEE :: A.C Fundamentals, Circuits and Circuit Theory
- For a sine wave with peak value Emax ___________ 8.30. the average value is
- Ohm is unit of all of the following except
- If resistance is 20 Q. and inductance is 27 in a R-L series circuit, then time constant of this circuit will be
- In a loss-free R-L-C circuit the transient current is
- Wire-wound resistors are unsuitable for use at high frequencies because they
- The series and parallel resonance on L-C circuit' differs in that
- At very low frequencies a series R-C circuit behaves as almost purely
- In an A.C. circuit power is dissipated in
-
