BIO Ventricular defibrillation During ventricular fibrillation, the muscle fibers of the heart’s ventricles undergo uncoordinated rapid contractions, resulting in little or no blood circulation. To restore the heart’s normal rhythm, a defibrillator sends an abrupt jolt of about -0.20 C of electric charge through the chest into the heart. How many electrons pass through the body during this defibrillation?

Key Concepts

Electric Charge

Electric charge is a fundamental property of matter that determines the electromagnetic interaction between particles. It is measured in coulombs (C) in the SI system and appears in various formulas and principles in physics, including current, electric force, and potential difference.

Elementary Charge

The elementary charge is the smallest unit of electric charge that is observed in isolated protons or electrons. Its magnitude is approximately 1.602 x 10?¹? coulombs, and it serves as a basic building block for calculating the total charge in macroscopic systems.

Charge Quantization

Charge quantization is the concept that electric charge exists in discrete, indivisible amounts that are integer multiples of the elementary charge. This principle is essential for understanding how the cumulative effects on a macroscopic scale arise from the contributions of individual electrons or protons.
