SUMMARY

The discussion focuses on calculating the resistance required for a pacemaker that sends 75 pulses per minute, with a capacitor charging to 0.25 V and a capacitance of 110 µF. The battery voltage is specified at 9.0 V. The key equations for determining resistance in this context involve the time constant of the RC circuit, which is critical for ensuring the pacemaker operates correctly.

Homework Statement


A pacemaker sends a pulse to a patient's heart every time the capacitor in the pacemaker charges toa voltage of 0.25 V. It is desired that the patient receive 75 pulses per minute. Given that the capacitance of the pacemaker is 110 uF and that the battery has a voltage of 9.0 V, what value should the resistance have?


Homework Equations


What value is the resistance?
