Step 1
For the AM antenna with a frequency range from 500 KHz to 1.6 MHz, we can use the formula for the resonant frequency of a parallel LC circuit: f = 1 / (2π√(LC)) Where f is the frequency, L is the inductance, and C is the capacitance. To find the range of Show more…

(I) The variable capacitor in the tuner of an AM radio has a capacitance of $2200 \mathrm{pF}$ when the radio is tuned to a station at $550 \mathrm{kHz}$. What must the capacitance be for a station near the other end of the dial, $1610 \mathrm{kHz?}$
The tuning circuit of an AM radio contains an $L C$ combination. The inductance is $0.200 \mathrm{mH}$, and the capacitor is variable, so the circuit can resonate at any frequency between $550 \mathrm{kHz}$ and $1650 \mathrm{kHz}$. Find the range of values required for $C$.
