Assertion : The value of current through `P - n` junction in the given figure will be `10 mA`.
Reason : In the above figure, p-side is at higher potential than n-side.

Options

A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Answer

B

Explanation

The `p`-side of `p-n` junction is taken is taken at higher potential than `n`-side so, `p-n` junction is forward biased. Taking its resistance to be zero and applying Ohm's law.
`I=V/R=(5-2)/300=10^(-2)A`
`=10^(-2)xx10^(3) mA=10 mA`
