What will happen if 120 volt appliance is plugged into 220 volt outlet explain with electrical equation?

If V is the rated voltage of the equipment, and Vs is voltage of the supply, we have this approximate equation: Vs = 2 V. That is enough to wreck the equipment and/or blow the fuse.

120 volt appliance on 240 volts
This senerio will use an electric baseboard heater but the results will be the same for any electrical appliance.
The heater will operate over its given specified wattage. A 120 volt heater run off of 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. A 240 volt heater can be run off of 120 volts but the wattage will be reduced.
For example if an ordinary 1000 watt baseboard heater's supply is 120 volts, the current of the heater will be, I = W/E 1000/120 = 8.3 amps.
The resistance of the heater is R = W/I (squared) =1000/8.3 x 8.3 (69) = 14.5 ohms.
Applying 240 volts on the same heater whose resistance is 14.5 ohms results in a new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/14.5 = 3972 watts.
This is 2972 watts, almost 300%, higher than the manufacturer's designed safety rating.
The amperage drawn by connecting a 120 volt, 1000 watt heater to a 240 volt source will be, I = W/E = 3972/120 = 33 amps.
W = watts, I = amperage, R = resistance in ohms and E = voltage.

What will happen if 120 volt appliance is plugged into 220 volt outlet explain with electrical equiation?
If the supply voltage is Vs and the equipment voltage is Va, then the equipment will work if Va = Vs (equation). But if Vs / Va = 220 / 120 (equation) the equipment will fail.
Can an appliance that is 115 volts 15 amps be plugged into a normal household electrical outlet in the untied states?
Yes, an appliance that is 115 volts 15 amps can be plugged into a normal household electrical outlet in the Untied States of America, also available in Canada. LOL
An appliance plug can be distinguished from other plugs by its?
permanent attachment to an appliance An appliance plug may have a differently shaped plug, in order to prevent it from being plugged into an ordinary electrical outlet (one with the wrong voltage or power rating).
If an appliance is plugged in but the switch is off the electrician should always consider the appliance as?
If an appliance is plugged in but the switch is OFF, the electrician should always consider the appliance as A. hazardous. C. safe. B. ungrounded. D. de-energized.
Why do electrical appliances need to be plugged into the wall?
Because the power needed to make them work is delivered by a national 'grid' of electrical cables. There is no way to actually transmit power to an appliance through the air. It must be deilvered by cables.

What is the function of electrical socket?
Its function is to supply electrical power via a plug that is plugged into it to supply an appliance.
How can electrical testing meters aid in the troubleshooting process of an appliance?
Electrical testing meters can definitely aid in the troubleshooting process of an appliance. This is because if it reads "no voltage" when plugged into the outlet, then the fuse or circuit is at fault, not the appliance.
Can leaving electrical appliances plugged in cause fires?
No, A plugged in appliance will not cause a fire. There has to be an outside fuel source that could catch the flame.

What does the french word branchee mean?

Does an appliance use power when not on?
If it is plugged in yes.
If an appliance is plugged in but the switch is off the electrician should always consider the appliance as?
