A heart pacemaker consists essentially of a capacitor in series with a resistor. In this idealized circuit, the capacitor suddenly discharges and sends a pulse to the heart when the capacitor voltage reaches a certain value. The charge-discharge cycle then repeats. Suppose a particular pacemaker is designed to send 72 pulses per minute using a 7.0 µF capacitor in a simple RC circuit. What value of resistance should be used if the pacemaker is to fire when the voltage reaches 48% of maximum? Incorrect: Your answer is incorrect. M\Omega
