When 10V,DC is applied across a coil current through it is 2.5A, if 10V,50Hz A.C. is supplied current reduces to 2A. Calculate reactance of the cell.

When 100V dc is applied across a coil a current of 1 A flows through it When 100V ac of 50Hz is applied across the same coil only 0.5A flows The resistance and inductance of the coil are ( take pi^(2) =10) .

When 100 V dc is applied across a coil, a current of 1A flows through it and when 100 V ac of 50 Hz is applied to the same coil, only 0.5 flows The inductance of coil is

A student connects a long air cored - coil of manganin wire to a 100 V D.C. supply and records a current of 25 amp. When the same coil is connected across 100 V. 50 Hz A.C. the current reduces to 20 A , the reactance of the coil is :-

When 100 V dc is applied across a coil, a current of 1A flows through it and when 100 V ac of 50 Hz is applied to the same coil, only 0.5 flows The resistance is

When 100 V DC is applied across a solenoid, a steady current of 1 A flows in it. when 100V AC is applied across the same solenoid, the current drops to 0.5 A. If the frequency of the Ad source is 150// sqrt3pi Hz , the impedance and inductance of the solenoid are

When 100" volt" dc is applied across a coil, a current of 1 amp flows through it, when 100 V ac of 50 Hz is applied to the same coil, only 0.5 amp flows. Calculate the resistance and inductance of the coil.

When 100 DC is applied across a solenoid, a steady current of 1A flows in it. When 100V AC is applied across the same solenoid, current drops to 0.5A. If the frequency of AC source is (50sqrt(3))/(pi) Hz, find the resistance and inductance of the solenoid.

When 100 volts DC is applied across a coil, a current of 1amp flows through it. When 100 volt AC at 50 cycles s^(-1) is applied to the same coil, only 0.5 ampere current follows.
