(a) The output voltage of a voltage regulator decreases by \(8 \mathrm{mV}\) as the load current changes from 0 to \(2 \mathrm{~A}\). If the output voltage changes linearly with load current, determine the output resistance of the regulator.

(b) If the output resistance of a voltage regulator is \(R_{o f}=10 \mathrm{~m} \Omega\) and the output current changes by \(1.2 \mathrm{~A}\), what is the change in output voltage?
