The current in the forward bias is known to be more (-mA) than the current in the reverse bias `(-mu A)`. What is the reason, then, to operate the photodiode in reverse bias ?

Assertion : E_(a) of the forward reaction is higher than that backward reaction in a reversible endothermic reaction. Reason: Increasing the temperature of the substance increase the fraction of molecules which collide with energies greater than E_(a) .

A straight horizontal conducting rod of length 0.45 m and mass 60 g is suspended by two verical wires at its ends. A current of 5.0 A is set up in the rod through the wires. a. What magnetic field should be set up normal to the conductor in order that the tension in the wires is zero? b. What will be the total tension in the wires if the direction of current is reversed keeping the magnetic field same as before? (Ignore the mass of the wires.) g = 9.8 m/s^(2) .

When forward bias is applied to a p-n junction, what happens to the potential barrier and the width of depletion region.
