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:
Both decreases
Explanation:
In forward bias arrangement of P-N junction diode, depletion layer and resistance both decrease.

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
