JEE Main 2014 Physics question

The current voltage relation of diode is given by mA, where the applied voltage V is in volts and the temperature T is in degree Kelvin. If a student makes an error measuring V while measuring the current of 5 mA at 300 K, what will be the error in the value of current in mA?

• (A)0.02 mA
• (B)0.5 mA
• (C)0.05 mA
• (D)0.2 mACorrect
