The currect voltage relation of a diode is given by `1 = (e^(van v//T) -1 )mA` where the applied volied `V` is in volts and the tempetature `T` is in degree kelvin if a student make an error meassurting `+- 01 V` while measuring the current of `5 mA at 300 K` what be the error in the value of current in `mA`A. `0.2 mA`B. `0.02 mA`C. `0.5 mA`D. `0.05 mA` |

Answer» Correct Answer - A The current voltage relat5ion of diode is `1 = (e^(1000V//T) - 1) mA `(given) when 1 = 5 mA, (e^(1000V//T)= 6 mA` `Also dl = (e^(1000V//T) xx (1000)/(T) (By exponential function) `= ( 6 mA) xx (1000)/(300) xx (0.01)` `= 0.2mA` |
