Do electric appliances like refrigerator burn by high voltage or low voltage?

Answer 1

I believe your question is: "Do electric appliances (like a refrigerator) BURN OUT due to high voltage or low voltage?"

Low voltage causes more problems for a motor than slightly high voltage. (Obviously a high voltage surge from lightning is going to damage all sorts of equipment.)

When running, AC motors are a "constant power" device. If the voltage goes down, they require more current to maintain operation. The higher amperage generates heat that can cause insulation failure in the motor (or other components)

In general, appliances are designed to reliably operate down to about 104 volts. The design assumptions are that the incoming voltage at the electric meter can be 110 volts and there is an additional voltage drop to the receptacle outlet where the appliance is plugged in.

That being said, let's look specifically at a residential refrigerator purchased in the US. Since 1992, refrigerators have been built with special technology to operate on voltages as low as 104 volts.

Back in the mid-90's there was a device known as the "Green Plug" that was supposed to save energy (and money) by running the refrigerator at the lowest possible voltage using a solid-state voltage regulating device. If you read the package, it said "not for use on refrigerators made after 1992" since that same technology was being installed at the factories.

Most homes have an incoming voltage far higher than 113 volts. Typically 115 to 120 volts, with some homes (near the substation) running in the high 120's.

Low Voltage Refrigerator

Answer 3

Did you ever get electrical shock ? Ask an electrician, without knowing anything physics of electricity, he will bluntly answer that is higher voltage. Let me go to a greater depth. Field Potential Electrical E (V/m) V ( Volt) Gravitational g m/s^2 V ( Jule ) Without taking positive, negative and direction both are same. Still g is constant at reasonable distance above earth( it does not depends on the potential energy of small body ) surface but not E at reasonable distance from electric charge. Therefore, it quite depends 1) size of charge producing field or voltage. 2) distance from the source and distance between two measuring points.

Answer 4

They burn by high voltage and make sure you have a fire extinguisher available and ready to use. Dont get burnt by the refrigerator.

Answer 5

They 'burn' power not high or low voltage. My fridge cools rather than burns anyway! Voltage maybe 240 or 110 depending on your abode.

Answer 6

Appliances do not burn. They draw current.

All appliances in you home except for your stove and dryer use 120V. Your refrigerator probably when running draws about 10 A.

Stoves and dryers use 240 V.

Answer 7

usually 117 in the u.s.
