A cylindrical wire of radius 0.5 mm and conductivity 5 xx 10^7 S/m is subjected to an electric field of 10 mV/m. The expected value of current in the wire will be x^3pi mA. The value of x is ____ .

A solenoid made up of copper wire consists of 400 turns and carries a current of 5 A. If length of the solenoid is 0.5 m and has a radius of 2 cm, find the magnitude of the magnetic field inside the solenoid.

The armature of a shunt wound motor can with stand current up to 8 A before it overheats and it damaged. If the armature resistance is 0.5 Omega ,minimum back emf that must be motor is connected to a 120 V line is

A P-N junction diode can withstand currents up to 10 mA . Under forward bias, The diode has a potential drop of 0.5 V across it which is assumed to be independent of current. The maximum voltage of the battery used to forward bias the diode when a resistance of 200 Omega is connected in series with it is

A rectangular loop has a sliding connector PQ of length l and resistance R (Omega) and it is moving with a speed v as shown. The set-up is placed in a uniform magnetic field going into the plane of the paper. The three currents I_(1), I_(2) and I are

A moving coil galvanometer gives full scale defection when a current of 0.05 A is passed through its coil it is converted in to a voltmeter reading up to 5V by using an external resistance of 975 omega what is the resistance of the galvanometer coil ?
