Why is it dangerous to touch a live exposed conductor?

• A. It can deliver a dangerous current, causing electric shock or burns.
• B. It will always cause instant death.
• C. It is safe if the area is dry.
• D. It cannot conduct electricity if insulated.

Answer: (A)

Touching a live exposed conductor is dangerous because electricity will flow through your body to complete the circuit. Your body can become the path to ground, and the amount of current that passes through depends on the voltage and your body’s resistance. Dry skin offers some resistance, but it’s not a guaranteed shield—conditions can change, and even a small amount of current can cause a painful shock, burns at the contact point, or more serious effects if the current travels through vital areas like the chest. Higher currents can disrupt breathing or the heartbeat. Insulation isn’t a guarantee of safety either; if the insulation is damaged or you touch the conductor through a gap, current can still pass. Wet conditions further reduce resistance and increase danger. The safest rule is to avoid touching exposed conductors entirely and to de-energize the circuit before any contact.
