A positron and an electron orbit one another at a distance \(\ell\) at speed \(v.\) What is the total power radiated by the pair?

What is the power radiated by an electron moving parallel to a uniform electric field \(\vec{E}\)?

A \( 200 \mu\text{F}\) capacitor is attached to \(10 \text{ V}\) AC source. What is the RMS current at a frequency of \(\dfrac{500}{\pi} \text{ Hz}?\)

What driving frequency is required for a \(L=2\text{ H}\) inductor to pull 2 A of current from an \(\varepsilon = 220 \text{ V}\) AC source?

An RLC circuit with components related by \(R=\sqrt{\frac{L}{C}}\) is tuned to half of its resonant frequency. What is the ratio of the current to the maximum ...
