What is the internal voltage and current in the US/Canada home appliances? The question is NOT quot;what is the input voltagebut what is the actual energy that makes the work - for example the power that drives the motor of a vacuum cleaner, or the power that makes your microwave work. I think, before the actual work is done, the current from the plug outlet is converted inside the device, and that converted energy is used to make the device work. So, what are the INTERNAL power/voltage/current of the following devices and are they AC or DC?: vacuum cleaner, microwave oven, fridge, and clothes dryer? What other devices are there that that have internal voltage/current of about 12-16 volts at 60-110 amperes, preferably at DC? Thank you.
household voltage is 120 volts ac. a typical household circuit is rated at 20 amps. if you were to think of electricity as water in a pipe, the voltage is the pressure. amperage is rate of flow. so in a water pipe you always have water pressure however you have no flow until you open the spigot. all the devices you named operate on normal 120 volt ac household current except an electric dryer which operates on 240 volts ac. the listed nameplate amperage or wattage is the current that is required to make the device work. there is no conversion of energy to make the device work. electromotive force is the force which drives a motor. items that heat such as a clothes dryer or incandescent light bulb work on a principle of electrical resistance. direct current is typically low voltage (1.5-24) and is the type of electricity found stored in batteries used in cars and flash lights, cell phones, etc. the only 12-16 volt 60-110 amp dc device would be an automotive type battery charger. hope i answered your question.
there is a spec come with all the appliance.check bak with ur manual.
Refrigerators and vacuum cleaners runoff 110 VAC internally though the refrigerator may also use a lower DC or AC voltage for control. A dryer uses 220 VAC internally. The microwave probably depends on the brand. I'm not sure what voltage the magnetron that makes the microwaves might use. The microwave, television, stereos and things like that probably use several voltages internally. It could be from 9 VDC to 48 VDC with different voltages at different points.
