Question

Why AC shocks are more dangerous than DC shocks?

• A. AC current magnitude is huge
• B. DC current magnitude is small
• C. AC reverses direction periodically causing an attractive force to the body on change of cycles
• D. DC cant find a complete electrical path

Answer 1

Answer: (C)

AC reverses direction periodically causing an attractive force to the body on change of cycles

When man comes in contact to a live wire, he/she generates same charge in the hand.

In DC, force is repulsive and also the person perceives this. So, he/she is quickly able to withdraw the hand.

In AC, due to continuously changing polarities, force becomes attractive and the neurons give false information to the brain. So, the hand gets stuck and may receive a severe shock.
