In a p-n junction, the magnitude of the drift current is lower than the magnitude of the diffusion current when the junction is
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → forward biased **
$\text{In a p-n junction:}$
$\text{Drift current is due to minority carriers, diffusion current is due to majority carriers.}$
$\text{At equilibrium: diffusion current = drift current in magnitude.}$
$\text{When forward biased: diffusion current increases, drift current remains nearly the same.}$
$\text{When reverse biased: drift current dominates, diffusion current decreases.}$
$\text{Hence, magnitude of drift current is lower than diffusion current when the junction is forward biased.}$
$\text{Answer: forward biased}$
