-
A coil is wound having a diameter d. Its inductance is 10 mH. If it is rewound on the same core with a wire having diameter 0.5 d and total weight of the wire is the same as before, the inductance will be
-
A resistance and an inductance are connected in parallel and fed from 50 Hz ac mains. Each branch takes a current of 5 A. The current supplied by source is
-
Assertion (A): The inductance of an iron cored solenoid is not constant.
Reason (R): BH curve of an iron specimen is non-linear.
-
An RC driving point impedance function has zeros at s = - 2 and s = - 5. The admissible poles are
-
A triangular Pulse of 10 V peak is applied to a capacitor of 0.4 F. The change of the capacitor and its waveform is
-
A 10 μF capacitor is charged from a 5 volt source through a resistance of 10 kΩ. The charging current offer 35 m sec. If the initial voltage on C is - 3 V is
