SOLUTION

The magnitude of electric shock on the human body primarily depends on Current flowing through the human body.

• Current Flow: The amount of electric current that flows through the body is the most critical factor determining the severity of an electric shock. Higher currents can lead to more severe physiological effects, including muscle contractions, respiratory arrest, and cardiac issues.
• Voltage Influence: Voltage is the “pressure” that drives the current, While voltage (line voltage) is important as it can influence how much current flows through the body (according to Ohm’s Law), it is ultimately the current that has the most direct impact on the body’s response to electric shock.
• Resistance: The body’s resistance also plays a role, as it determines how much current will flow for a given voltage. However, the specific current flowing through the body is what directly affects the physiological outcomes.
