In this problem, we will find the value of resistance from the expression of voltage across a charged capacitor, which is expressed as:
The voltage, V = 0.732V0
We get time taken by the heart pacemaker to fire once as:
t = 1min/69 = 60s/69 = 0.8696 s
A heart pacemaker fires exactly 69 times a minute, each time a 29.0 nF capacitor is charged (by a battery in series with a resistor) to 0.732 of its full voltage. What is the value of the resistance?
