The current voltage relation of diode is given by I = (e 1000V/T – 1) mA, where the applied voltage V is in volts and the temperature T is in degree Kelvin. If a student makes an error measuring ± 0.01 V while measuring the current of 5 mA at 300 K, what will be the error in the value of current in mA ?

1. 0.02 mA
2. 0.5 mA
3. 0.05 mA
4. 0.2 mA

Correct answer: 0.2 mA
