A puppy was trapped by a current carrying wire and was barking for help, a little boy can't stop himself and rushed for help and tried to save the dog by his naked hands but was caught himself. A man passing nearby took a wooden stick and saved both of them. Why did he use a wooden stick?

Wood is a poor conductor of electricity. It does not allow electric current to flow through it easily and is a poor conductor of electricity. But human body is a good conductor of electric current and that’s why when the little body tried to save the dog,he got trapped because current also started flowing through his body.
