Figure P32.41 shows resistors (R_{1}=30.0 Omega) and (R_{2}=) (10.0 Omega) connected in parallel to an (mathrm{AC}) source.

Question:

Figure P32.41 shows resistors $R_{1}=30.0 \Omega$ and $R_{2}=$ $10.0 \Omega$ connected in parallel to an $\mathrm{AC}$ source.

(a) If the maximum current in the circuit is $2.03 \mathrm{~A}$, what is the amplitude $\varepsilon_{\max }$ 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 $t=20.2 \mathrm{~ms}$ ?
