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

If two physical quantities a and b are related by the equation a= kb where k is dimensionless constant, then the principle of dimensional homogeneity demands that a and b have the same dimension. However the proportionality constant k cannot be determined by dimensional analysis only. It may at most be written that a prop b if a and b are of the same dimension.
