Consider a series circuit containing a resistor of resistance R and a capacitor of capacitance C connected to a source of EMF & with negligible internal resistance. The wires are also assumed to have zero resistance. Initially, the switch is open and the capacitor discharged. (Figure 1) Let us try to understand the processes that take place after the switch is closed. The charge of the capacitor, the current in the circuit, and, correspondingly, the voltages across the resistor and the capacitor will be changing. Note that at any moment in time during the life of our circuit, Kirchhoff's loop rule holds and, indeed, it is helpful: E-VR-Vc = 0, where VR is the voltage across the resistor and Vc is the voltage across the capacitor.

CURRENT DECREASING TO ZERO: Previously we found the current immediately after a circuit is changed and the current a long time after. Now we want to know how the current I(t) depends on time, not just at t= 0 and at t = 00, 1. Assume the switch is in position (b). Applying the loop rule around the right loop counterclockwise gives dl (t) ZAVAV₁-1(t)R = -L- - I(t) R = 0 dt where I (t) is the current at time t.

Substitute 1(t) = A e-t/TL into both the left and right hand side of the…An oscillator circuit is important to many applications. A simple oscillator circuit can be built by adding a neon gas tube to an RC circuit, as shown in the figure (Figure 1). Gas is normally a good insulator, and the resistance of the gas tube is essentially infinite when the light is off. This allows the capacitor to charge. When the capacitor voltage reaches a value Von, the electric field inside the tube becomes strong enough to ionize the neon gas. Visually, the tube lights with an orange glow. Electrically, the ionization of the gas provides a very-low-resistance path through the tube. The capacitor very rapidly (we can think of it as instantaneously) discharges through the tube and the capacitor voltage drops. When the capacitor voltage has dropped to a value Voff, the electric field inside the tube becomes too weak to sustain the ionization and the neon light turns off. The capacitor then starts to charge again. The capacitor voltage oscillates between Voff, when it starts…
