The currect voltage relation of diode is given by `1=(e^(1000 V//T)-1) mA`, where the applied voltage V is in volt 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 error in the value of current in mA?A. `0.5 mA`B. `0.05 mA`C. `0.2 mA`D. `0.02 mA` |

Answer» Correct Answer - C Given current `I=(e^(1000 V//T)-1) mA` `rArr 1+1=e^(1000V//T)` `dI=1000/T[e^((1000V)/T)]dV` `dI=1000/T[I+1]dV` `1000/300 [6]xx(0.01)` `dI=0.2 mA` |
