A signal generator having a source resistance of 50\(\Omega\) is set to generate a 1 kHz sinewave. Open circuit terminal voltage is 10 V peak-to-peak. Connecting a capacitor across the terminals reduces the voltage to 8 V peak-to-peak. The value of this capacitor is \(\underline{\hspace{1cm}}\) \(\mu\text{F}\). (Round off to 2 decimal places.)
Two single-core power cables have conductor resistances 0.7\(\Omega\) and 0.5\(\Omega\), and insulation resistances 600 M\(\Omega\) and 900 M\(\Omega\). When joined in series, the ratio of insulation resistance to conductor resistance is \(\underline{\hspace{1cm}}\) \(\times 10^{6}\).
