Question
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.
