Find the applied reverse bias potential if the transition capacitance of a silicon diode is \(4 \mathrm{pF}\) but the no-bias level is \(10 \mathrm{pF}\) with \(n=1 / 3\) and \(V_{K}=0.7 \mathrm{~V}\).

Determine the temperature coefficient of a 5-V Zener diode (rated \(25^{\circ} \mathrm{C}\) value) if the nominal voltage drops to \(4.8 \mathrm{~V}\) at a temperature of \(100{ }^{\circ} \mathrm{C}\).
