The figure shows the circuit of a flashing lamp, like those attached to barrels at highway construction sites. The fluorescent lamp L (of negligible capacitance) is connected in parallel across the capacitor C of an RC circuit. There is a current through the lamp only when the potential difference across it reaches the breakdown voltage V₁; then the capacitor discharges completely through the lamp and the lamp flashes briefly. For a lamp with breakdown voltage V₁ = 63.2 V, wired to a 92.4 Videal battery and a 0.102 mF capacitor, what resistance R is needed for 3 flashes per second?

The RC circuit shown in (Figure 1) can be used in an artificial pacemaker to establish a normal heart rhythm by generating periodic electrical impulses. The box labeled "controller" behaves as an open circuit until the voltage drop across the capacitor reaches a preset limit. Once that limit is reached, the capacitor discharges its stored energy in the form of an electrical impulse to the heart, starts to recharge, and then the process repeats.
