What happens if two 120 volt loads are connected in series to a 240 volts service?

Burn correctly if they were ordinary light bulbs having the same power rating.

However, if the loads were different, such as a 100 watt lamp and a 40 watt lamp - neither of them would produce the same amount of light.
If the loads were of very different types - say a 120 volt motor, which is a magnetic device, and a 120 volt computer, which is an electronic device - you can't say for sure how well they would each work when connected together in series across a 240 volt service without knowing a lot more facts about them.
What happens will always depend on the individual resistances and impedances of each load and how different they are.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 12y agoYou would let all the smoke out of both loads. Being connected in parallel would connect each load with 240 volts instead of the required 115 volts, resulting in over-voltage to both devices. The only way two 115 volt loads could be connected to 240 volts would be to be in series and both loads would have to be equal amperage draw to achieve correct and safe operation. It is not recommended to do this unless you have good knowledge about electrical. Your question seems to indicate that you don't have the knowledge to do this safely. It is recommended that you leave this to an expert electrician.

∙ 11y agoIn the series circuit if the two loads have equal resistance then the voltage will split the 240 volts to 120 volts across each load.
Putting electrical loads into a series connection inadvertently, is the reason that the neutral wire on a 120/240 North American service distribution is never opened or switched.

∙ 11y agoNothing happens. That is the way that combined loads are connected from a service distribution panel. If there is only one load on the circuit from the distribution panel it can also be classed as a series connected load. More than one load on the circuit then the classification is changed to parallel.

Is TWO OR MORE batteries and two or more loads can be defined as series circuit Or a series circuit has only just ONE source (battery) and 2 or more loads?
Your question is very muddled and it is difficult to understand exactly what you are asking. Something is in "series" if it is connected in the circuit as a "daisy chain". Thus both loads AND batteries may be placed in series.
What is calculated load?
A calculated load in electrical terminology is the sum of all of the loads that are connected to a system. To size a service distribution for a home all of the connected loads have to be calculated in. Some loads can be derated as per the electrical code. When the total amperage is calculated from the sum of all of the loads, the wire size and distribution can be sized to handle the calculated load.
What happens when heavy loads are connected to an electrical generator?
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
Why does less current run through a circuit when there are more loads?
This happens only in pure series circuits, due to increased resistance.
Four loads are connected in series across 120 volts dc 3 amperes current exists one load fail to operate?
Your description of the system is either contradictory or incomplete, therefor no answer can be given.
what Type of circuit is one in which all loads are connected in one single loop?
series circuit
When are series circuits useful-?
when loads act as switches
A circuit in which loads are connected side is called?
Loads are connected side
How are loads connected in a series circuit?
To be a Series circiut the electricity MUST flow THROUGH one load to the next."added"

What happens if a fuse is connected into the neutral wire?
In North America the neutral wire is never fused. This is because of the three wire circuit that uses a common neutral. If there are two loads connected across a common neutral circuit and the neutral opens a 230 volt supply will be impressed across both loads as they are now in series with the supply. If both loads were balanced then the voltage drop across both loads would be equal. Dropping 120 volts across each load. Where the problem arises is if the two loads are not balanced and voltage drop goes higher than the manufactures recommended voltage, then the connected device could burn out.
What happens if you add more loads to a series?
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.

Is electric cooker connected in series or parallel?
All residential loads are connected in parallel, so that they share the same supply voltage, which is necessary for them to develop their rated power outputs.
What is a circuit in which loads are connected side by side?
A circuit in which loads are connected side by side is known as a parallel circuit.
What happens to the energy as it goes around a series circuit?
What do you mean by energy? amps? Volts?, Either way if you have a series circuit with 3 loads in the circuit all voltage will be dropped proportionally to the loads resistance, if that makes any sense.
