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 is a two-way switch and how does it function in electrical circuits?
A two-way switch is a type of electrical switch that allows control of a single light or appliance from two different locations. It has two terminals that are connected to the power source and two additional terminals that are connected to the light or appliance. When the switch is flipped, it changes the direction of the current flow, either turning the light on or off. This allows the light or appliance to be controlled from multiple locations in a room.
What does an electric appliance use up in its operation?
An electric appliance uses up electrical energy during its operation to power its components and perform its intended functions. This energy is typically supplied through a power source such as an electrical outlet or battery.
How many terminals does a voltage source have?
One
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.
When a wire is connected to both terminals of an electrical source is called?
When a wire is connected to both terminals of an electrical source, it forms a closed circuit. This allows current to flow from the source, through the wire, and back to the source, completing the electrical circuit.

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.
When you turn on a light or other electric appliance you close a circuit?
Yes, turning on a light or electric appliance completes a circuit by allowing current to flow from the power source, through the appliance, and back to the power source. This flow of electrons enables the appliance to function and produce light or perform its intended task.
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.
Why can't i connect a 220v appliance directly to a 110v power source?
Connecting a 220V appliance to a 110V power source can damage the appliance and potentially cause a fire. The appliance is designed to run on 220V input, so using a lower voltage can overload its components. It's important to use the correct voltage to ensure safe and proper operation.
Why do all electrical appliances have terminals?
To allow the wires to be connected to a source of electricity.
What is the source that maintains a constant value of potential energy in its terminal?
A battery is a source that maintains a constant value of potential energy in its terminals. The chemical reactions within the battery create a potential difference between its terminals that remains constant as long as the battery is in good condition.
