What happens if the same 120V source is supplied to both hot terminals of a 240V appliance?

I can see the need for this question. The power goes out frequently around my house. I have a generator that only puts out 110VAC. I made a special adapter to plug it into the breaker box. I made it so both legs in the box are live. This way, I have power anywere in the house. Of course I turn off the main breaker, but I also keep the 220VAC breakers off. The appliance will function but it will be taking twice as much current from one leg of the mains instead of equal amounts from both legs. If the total power required by the appliance is too high - and other appliances, lamps, or whatever plugged into that same leg are taking their normal loads - this way of supplying the 240V appliance may cause the main breaker for that single leg to trip. If that happens you must stop supplying the 240V appliance in this way or at least turn off all the other appliances running from that leg until the breaker stays "on" quietly and safely. Remember that such 240V appliances, as supplied for 60Hz systems as in US or Canada, are designed to run on two "hot" legs (Black and Red), not just one leg. So this kind of "double hooking-up" should really only be tried in emergencies, as the Answer above describes. why would you even ask such a question? The appliance will not function.

What happens when you plug a 110 volt appliance into a 220 volt source?
The 110 appliance will run faster than normal and burn out.
What happens to the power supplied by the source as more resistors are added in parallel to a constant voltage source?
increases
What happens when the voltage supplied to a circuit remains constant and the circuits resistance decreases?
When the voltage supplied to a circuit remains constant and the circuit's resistance decreases, the current drawn from the source must increase.
How many terminals does a voltage source have?
One
What happens if you plug a 220 volt appliance into a 240 volt outlet?
They are the same, just different ways of describing it. You should also be sure the frequency is the same--50Hz vs. 60Hz. In general, if the appliance and the source are wired properly, the plug will only connect if the source is compatible.
Why current source is replaced by open circuit across the terminals?
For an ideal current source, this means replace the current source with an open circuit. Resistance can then be calculated across the terminals.
What happens when a 120 volt appliance is plugged into a 240 volt source?
If it's a true 120 V only appliance, and not a dual-use appliance it will most likely break immediately. There may be a fuse in the unit, which can be replaced the unit to get it working(with the right voltage) again, or the unit may be permanently destroyed.
What happens if load torque is same at all speed in separately excited dc motor?
It means that the armature must be supplied with a constant-current source.

Why do all electrical appliances have terminals?
To allow the wires to be connected to a source of electricity.
What happens when an ac transformer attached to ac appliance is plugged into dc power source?
it depends on the transformer size and the period of time involved if continuous it should just blow the breaker and itself.
What is the source for mechanical motion supplied to a generator called?
friction
