Question

1. If a person touches a live wire, will he get stuck to it?
2. Why do we use copper wires as connecting wires?
3. A wire is carrying a current. Is it charged? If not, why?

Answer 1

1. Sometimes. Even very small currents are enough to disorganise our nervous system. Hence the affected person may temporarily lose his ability to exercise his nervous control to free himself from high voltage points.
2. A good conductor, low resistivity, and can be shaped to any size.
3. No. The net charge in the wire is zero even in the conducting state.
