Why are pin plug used in electrical appliances made from plastic and not from metal?
electric plugs and switches are made of plastics because they are more safer than other materials like iron,copper etc which conduct electricity which is very dangerous while switching plugs so switches and plugs are made of plastics .
Why electric plugs are made of plastic?
Plastics are poor conductor of electricity and resistant to heat, so they do not allow the electric current to pass through them making them safe to handle. So they are used to make electric switches and plugs.
Why are electric switches made of plastic and not metals?
Switches are made up of plastics or bakelite and non metals because plastics are bad conductor of electricity so they will protect us from shock and metals are good conductor of electricity so they will produce shock to our body..
Why do some appliances have 2 pins?
3 Answers. Many appliances in the USA and elsewhere have two-prong plugs because they are “double insulated.” The third prong is for ground fault protection except where outlets have been designed with protective shutters on the current-carrying slots that are opened by the ground prong.
Why are pin plugs made of metal?
The Plug. The pins inside the plug are made from brass because brass is a good conductor of electricity. The fuse sits between the pin and the terminal and breaks the electrical circuit if the electrical current is too great.
Why electric plugs and switches are made of thermosetting plastic?
(b) Electric plugs/ switches/ plug boards are saucepan is made of thermosetting plastic because it is a bad conductor of electricity. The electric current does not pass through such plastics.
Why are switches in a circuit made up of metal?
The contact material is chosen for its resistance to corrosion, because most metals form insulating oxides that would prevent the switch from working.
Why is a pin used in a plug?
A plug connects a device to the mains electricity supply. The cable between the device and the three-pin plug contains three copper wires that are coated with plastic….Plugs.
| Features of a plug | Function |
|---|---|
| Live wire | Copper wire coated with brown plastic along which the current enters the device |
Why do some appliances have 3-prong plugs?
When you plug in a three-pronged plug, that third prong is providing an alternate pathway for electricity in the event of a fault. If you cut the third prong off of a plug, you defeat the safety feature. Also, adapters were designed to use the cover screw to complete a ground circuit on some older plug designs.
What kind of material are plug pins made out of?
Many plugs use essentially raw brass (which has a gold-like tone). Or the ones that have a silver-looking tone likely have a nickel plating which prevents the brass from tarnishing and discoloring. That said, You are quite unlikely to find the kind of pins used in mains plugs as commodity items.
Why are electric plugs and switches made of plastic?
Other materials used for switches are ceramic switches, glass switches, and polymer switches. Electric plugs and switches are made of plastics because they are more safer than other materials like iron, copper etc which conduct electricity which is very dangerous while switching plugs so switches and plugs are made of plastics.
Why is it important to cover electrical wires with plastic?
Electricity is very dangerous and can kill. Perhaps the most important reason why electrical wires are covered in plastic is to protect people from electrical shock. Electricity is a dangerous form of energy and it can kill. Covering electrical wires in plastic guarantees that the electrons flowing through the wires will not flow
Why is the earth pin of some 3 pin plugs made of plastic?
Although there is no use of the pin because.. But still the plastic pin is given because there are some sockets which come with the earth pin protection The manufacturers design the sockets such that the earth pin gets inserted first then the opening for live and neutral pins opens mechanicaly…
