QUESTION 13 Resistor R and capacitor $C_1 = 18.6 \mu F$ are connected in series to an AC source with frequency 59.6, and rms current $I$ flows in the circuit. If the first capacitor is now replaced by a second capacitor $C_2 = 775 \mu F$, the rms current increases to 2.69I. Find R, in $\Omega$. QUESTION 14 Resistanceless coil $L = 40.2 mH$ and resistor $R = 66.9 \Omega$ are connected in series to an A.C. power source, voltage V and frequency f. If the frequency is increased from f to 4f, the rms current drops from I to 0.732I. Find the original frequency of the A.C. source, in Hz.
