Kirchhoff's Loop Rule Practice Test

A circuit contains an ideal battery $$\mathcal{E}$$, a resistor $$R_1$$, a capacitor $$C$$, and an inductor $$L$$. The resistor and inductor are in one parallel branch, while the capacitor is in another parallel branch. This parallel combination is in series with the battery. The switch is closed at $$t=0$$.

In a simple series circuit, a $$12,\text{V}$$ ideal battery is connected to a $$2,\Omega$$ resistor and a $$4,\Omega$$ resistor. The negative terminal of the battery is connected to a point defined to have zero potential. A clockwise current flows in the circuit from the positive terminal.
