(b) no current flows

(c) potential barrier across junction increases

(d) depletion layer resistance increases

The reason of current flow in P-N junction forward biase is

find the net current flowing out of the battery and potential at B.

The displacement current flows in the dielectric of a capacitor when the potential difference across its plates-

The displacement current flows in the dielectric of a capacitor when the potential difference across its plates-

Two capacitors of capacitances 2C and C are connected in series with an inductor of inductance L . Initially, capacitors have charge such that V_B - V_A = 4V_0 and V_C- V_D = V_0 . Initial current in the circuit is zero. Find (a) maximum current that will flow in the circuit, (b) potential difference across each capacitor at that instant, (c) equation of current flowing towards left in the inductor.

When a p-n junction diode is reverse biased the flow of current across the junction is mainly due to

The drift current in a reverse-biased p-n junction increases in magnitude if the tempareture of the junction is increased. Explain this on the basis of creation of hole-electron pairs.

A current 0.2 A flows in a wire of resistance 15 Omega . Find the potential difference across the ends of the wire.

The reverse-biased current of a particular p-n junction diode increases when it is expoesed to light of wavelength less than or equal to 600nm.Assume that the increases in carrier concentration takes place due to the creation of new hole-electron pairs by the light.Find the band gap.

When a current of (2.5 +- 0.5) ampere flows through a wire, it develops a potential difference of (20 +- 1) volt, the resistance of the wire is
