In the given circuit input voltage Vin is 3V and V2 is 1V. The resistance R1 is 1.5K. Cut-in voltage of diode is 0.5V. Forward bias resistance is 10Ω. The current I will be __________

In the given circuit input voltage Vin is 3V and V2 is 1V. The resistance R1 is 1.5K. Cut-in voltage of diode is 0.5V. Forward bias resistance is 10Ω. The current I will be __________ Correct Answer 1.33mA

Since both voltage sources are reverse bias to the diode, diode in the circuit disappears and equivalent circuit becomes as follows So current I = V1-V2/R = 3-1/1.5k = 1.33mA.
