Q: What type of plug is generally used on metal appliances?


Read this paragraph and choose the correct option from the provided answers:

A three-prong plug is generally used on metal appliances. The two flat prongs carry current to and from the appliance. The round prong is for safety. It connects with a wire inside the outlet that goes down into the ground. If any stray current leaks from the circuit or if there is a short circuit, the ground wire carries the current into the ground, which harmlessly absorbs it.

 Choices:

- 4 prong

- .2 prong

- 5 prong

- 3 prong


A:
3 prong
