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.
in case of ideal voltage source we consider the internal resistance to be zero.but in practical,every battery has some internal resistance then if you connect a load resistance across the terminals of that source,the net potential difference's across the voltage source will be a function of external resistance connects it won't give constant voltage across it's terminals.
In parallel connection all the positive terminals are connected with positive of the source and all the negative terminals are connected to negative of the source. Whereas in series connection one positive terminal is connected to the negative of another, like wise it goes on and finally the positive end is connected to the negative of the source.
A voltage source (V) is modeled by connecting its internal impedance (Zg) in series. If we determine the impedance across the voltage source terminals, it should be Zg, and it is possible only if the voltage source is short-circuited.An equivalent current source is modeled by connecting the current source (V/Zg) in parallel with the internal impedance Zg. For the two sources to be equivalent, their impedances across their terminals must be equal. This is possible only if the current source is open-circuited.
If they didn't, and the wires touched, all energy would be spent on a short-circuit at the point of contact rather than on powering the appliance. Also, if a bare wire touches the appliance, that itself would start to carry an electric charge, giving anybody who touched the appliance a nasty and dangerous shock.
