A circuit is constructed using the following materials: an ideal
battery, a switch, an uncharged capacitor, and n = 3 resistors.
The battery, switch, and capacitor are all connected in series.
with each other (in that order); then the resistors are all con-
nected in parallel to each other, and then placed between the
capacitor and the battery. The battery has emf & = 12.0 V,
the capacitor has capacitance C = 490 μF, and each resistor
has resistance R = 320 kn. At t = 0, the switch is closed. How
much energy E does the capacitor store when t 1.0 min? For
the limit check, investigate what happens to E as the number.
