What happens if you plug a 110V into a 220V outlet?

When we connect a 110V device, for example, to a 220V outlet, it will burn because it is not prepared for that electrical voltage. In this case, it will be necessary to use a voltage transformer. They will convert the 220 volts of voltage from the outlet to the 127 volts of voltage accepted by your appliance.
