Answer:
1. Electrical hazard or electrical shock is a condition due to direct or indirect electrical contact with energized conductor or equipment, and from which a person may sustain electrical injury from shock or damage to property or both.
2. These devices are designed to automatically shut off power to the circuit when problems occur. The "fix" is to. In the case of circuit breakers, the immediate answer is to find the breaker that has tripped and reset the lever to the ON position
3. A fuse or circuit breaker prevents this by ''blowing,'' or breaking the circuit, when an overload occurs. Fuses screw into threaded sockets inside the fuse box. The fuses contain a thin strip of metal that melts if the current (or amperage) flowing through that circuit exceeds the amount for which that fuse is rated
4. Earthing is a proper connection of exposed metal parts to electric circuit from ground. To avoid the risk of electric shock metal body of an electric appliances is earthed. This is used as safety measure especially for those appliance that have metallic body for example electric iron, toaster etc
5. Touching
6. Least or Lessen resestance
7. A short circuit is a condition when conducting wire touches the metallic part of the appliances, potentially causing electric shock to anyone who will able to touch the appliances.
