Question:

Figure P32.41 shows resistors \(R_{1}=10.0 \Omega\) and \(R_{2}=20.0 \Omega\) connected in parallel to an AC source.

(a) If the maximum current in the circuit is \(12 \mathrm{~A}\), what is the amplitude \(\mathscr{E}_{\max }\) of the AC source?

(b) If the source emf peaks at \(t=0\), and the frequency is \(60.0 \mathrm{~Hz}\), what is the potential difference across each resistor at \(t=12.5 \mathrm{~ms} ?\)
