To study the behavior of circuit containing a resistor and a charged capacitor when the capacitor begins to discharge. A capacitor with capacitance C is initially charged with charge q. At time t = 0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R (Figure 1) Part AWhat happens to the charge on the capacitor immediately after the switch is thrown? The electrons on the negative plate of the capacitor are...

An electrical circuit contains an electromotive force
An electrical circuit contains an electromotive force \(E\) (supplied by a battery or generator), a resistor \(R\), an inductor \(L\), and a capacitor \(C\), in series. If the charge on the capacitor at time \(t\) is \(Q-Q(t)\), then the current is the rate of change of \(Q\) with respect to \(t: I=\frac{H Q}{d w}\). Kirchhoff s voltage law gives the supplied voltage as:$$ L \frac{d i}{w}+R t+\frac{R}{E}=E(t) $$Since \(I=\frac{1}{1}\), the differential equation becomes:$$ L Q^{\prime \prime}+R Q^{\prime}+\frac{1}{c} Q=E(0) $$with initial...
