On adjusting the P-N junction diode in forward bias,
Options
(a) Depletion layer increases
(b) Resistance increases
(c) Both decreases
(d) none of these
Correct Answer:

Becoz width of depletion layer decreases in forward bias and hence allows more current to move i.e.conductivity increases and resistivity decreases ..so both decreases OPTION (C) is correct
