Question

A heart defibrillator being used on a patient has an RC time constant of 9.5 ms due to the resistance of the patient's body and the capacitance of the defibrillator.

If the defibrillator has an 9.5 μF capacitance, what is the resistance of the path through the patient in kΩ? (You may neglect the capacitance of the patient's body and the resistance of the defibrillator.)

Answer 1

RC time constant is given by the product of Resistance and capacitance.

so t= RC

R= t/C

R = (9.5*10-3 ) / (9.5 * 10-6)

R = 103 ohm

or R = 1kilo ohm
