Question

A silicon diode conduct 5 Mili ampear at room temperature forward bias condition at 7 volt calculate its reverse saturation current and if now forward voltage is increased to 0.75 volt calculate the new current flowing through the diode​

Answer 1

Answer:

mark me as brilliant

Explanation:

The given diode is Silicon Diode , hence n = 2. First, we will check all the given things, and after that we will check the things which we have to find.

Now, Diode Current, Id = 10 mA

Reverse Saturation Current, Is = 25 * 10^(-7) A

Temperature = 300'C

Forward Bias Voltage = Vd

We use the formula, Id = Is . ( e^Vd/nVt - 1 )

So now, Put all the given values in the equation, and hence we have get the Vd.

Vd = approx ( 0.18 V )

Hope it helps.
