State three factors that determine the level of an electric shock.

1. Voltage: The higher the voltage of the electric current, the more severe the shock is likely to be. Higher voltages can cause more damage to the body's tissues and organs.

2. Current: The amount of current flowing through the body also plays a significant role in determining the level of an electric shock. Higher currents can cause more severe muscle contractions and potentially lead to cardiac arrest.

3. Duration of exposure: The length of time that a person is exposed to an electric current also affects the severity of the shock. Longer exposure times can lead to more serious injuries and complications.
