A 2.96 F defibrillator capacitor is charged to 1.70x103 V. What is the resistance of the patient's chest ir, Answer

Explanation / Answer

Answer 1-

Thecombination of resistors can be seen as (R1 + R2) parallel to (R3 +R4) with V being the potential difference across each

R1 + R2 = 11 + 13 = 24

R3 + R4 = 10 + 10 = 20

Current through R1 & R2 = I1 = V/(R1 + R2) = 28/24 = 1.167 A

Current through R3 & R4 = I2 = V/(R3 + R4) = 28/20 = 1.4 A

Potential difference across R1 = I1R1 = (1.167)(11) = 12.837 V

Potential difference across R2 = I1R2 = (1.167)(13) = 15.171V

Potential difference across R3 = I2R3 = (1.4)(10) = 14V

Potential difference across R4 = I2R4 = (1.4)(10) = 14V.
