Does voltage cause Electric Shock?

Electric shock is caused by the current that flows through the body. Voltage is the potential difference that can push that current through, but it is not the direct cause of the shock. The amount of current that flows (and thus the risk of harm) depends on the voltage and the body's resistance (I = V/R). For example, dry skin has higher resistance and may limit current, while wet skin or a path that bypasses resistance allows more current to flow. Since the actual harmful effect comes from the current, not the voltage alone, the correct understanding is that current causes electric shock.
