Why is AC plug different?
At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to a wider stream flowing slowly. And less current allows for thinner wires. Since the copper that’s used for electric wires is expensive, higher voltage could save money.
What are 3 prong outlets called?
GFCI Outlet – Also known as Ground Fault Circuit Interrupter, GFCIs are three-prong outlets with an added safety mechanism to prevent shock. When a current is too strong or on an unintended path, a GFCI quickly shuts off power to lessen the severity of the shock.
Is a wall outlet AC or DC?
When you plug things into the outlet in your house, you don’t get DC. Household outlets are AC – Alternating Current.

Electrical grade outlets normally use a 125V, 15A straight blade receptacle.
Does AC need special plug?
A good rule of thumb is that units with a rating higher than 15,000 BTUs will require a dedicated 220-volt circuit. Some air conditioners also feature a non-standard plug, indicating that it may require a dedicated circuit.
What are the 3 types of connectors?
By Michael Pecht and San Kyeong electrical connectors
Electrical connectors are classified into three types based on their termination ends: board-to-board connectors, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors.
Which socket is used for AC?
AC power plugs and sockets connect electric equipment to the alternating current (AC) power supply in buildings and at other sites. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type.
Can AC run on normal socket?
The lower two voltage ratings are common in smaller units, while units with a rating higher than 15,000 BTUs will require a 220-volt circuit. Smaller units with a 115 volt and 15 amp requirement will be able to operate off a standard household outlet.
What are the two types of sockets?
Sockets come in two basic types—connection-oriented and connectionless. These terms refer to types of protocols.
Why are there different plug types?
The reason why the world is now stuck with no less than 15 different styles of plugs and wall outlets, is because many countries preferred to develop a plug of their own, instead of adopting the US standard.
What does A Type C plug look like?
Type C (electrical socket/electrical plug)

What is A universal outlet?
Proven in service with airlines throughout the world the IFPL Universal Power Outlet is designed to deliver 110V AC power to passengers’ devices; enabling passengers to use and charge their own mains powered electronic devices, e.g laptops and DSLR cameras, from the comfort of their seat.
When should I use 20 amp outlets?
Large consumers, especially kitchen appliances, such as microwaves, blenders and toasters, need a dedicated 20 amp circuit, to ensure a constant energy flow, which means they cannot share the circuit with other devices.
How do I know if my outlet is 15 amp or 20 amp?
