Two capacitors can be connected in series to double the voltage rating, but they must be identical capacitors and they should each have a resistor in parallel to equalise the voltages, the resistors chosen to pass about 1 mA.
With two capacitors in series the overall capacitance is half the capacitance of either capacitor. The combination stores equal charge at double the voltage and the stored energy is doubled.

How you can produce 240 volts from a single phase 3 wire system with a nominal voltage of 120 volts?
you can use two hot wire different phases with a double pole braker .
How can i get 16 volts from two 8 volt batteries?
To obtain 16 volts from two 8-volt batteries, connect them in series. This involves connecting the positive terminal of the first battery to the negative terminal of the second battery. The remaining free terminals (the negative terminal of the first battery and the positive terminal of the second battery) will provide the combined voltage of 16 volts. Ensure that both batteries are of the same type and capacity for optimal performance.
If you have two 1.5-V batteries and they have the positive terminal of one batery connected with the negative terminal of another how does that voltage compare with the voltage of a single battery?
When you connect the positive terminal of one 1.5V battery to the negative terminal of another, you create a series circuit. In this case, the voltage is additive, so the total voltage across the two batteries is 3V (1.5V + 1.5V = 3V), which is double the voltage of a single battery.
How do you change a heater from 120 volts 3a to 240 volts 1.5 a?
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
The air conditioning work in 230 volt why the compressor use capacitors of 370 and 440 volts if he only need mfd to start?
An AC capacitor is composed of two DC capacitors with the foil ends (-) connected together and the center ends (+) connected to the outside. There are variations to the connections. Each capacitor has to have the voltage rating required by the application -- and there are two capacitors in series in an AC capacitor. A 230V AC capacitor, depending on manufacturing design standard, may not be suitable for starting a 230V air conditioner.
What is formula for connecting 2 capacitors in parallel?
The result of connecting two capacitors in parallel is a new capacitor whose capacitance is the sum of the values of the two you connected up. Note. the safe working voltage is equal to the lower of the two working voltages on the two capacitors.
Is there a single phase capacitor?
All capacitors fundamentally have two sides or "connections" so that any single capacitor will have two terminals. That is true whether capacitors are used in single phase (using one or more capacitors), or in three phase power (same number of discrete capacitors on each phase). The packaging of capacitors is mostly as "singles" having just two connecting wires or terminals, but certain applications - such as three-phase motor speed controllers - often use "blocks" of three or more capacitors, packaged together into one "body" or "casing". Those "capacitor blocks" have four or more connecting wires or terminals.
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
What is the best knot for connecting two ropes?
The best knot for connecting two ropes is the double fisherman's knot.
What will happen to battery capacity if two batteries are joined?
Connecting two 12 volt batteries together in series would doubled the amp hours ie 125amp hour +125amp hour = 250amp hour and the voltage stays the same at 12 volts. Connect them in parallel and the voltage will double to 24 volts and the amp hours will stay the same ie 125 amp hours.
Can you replace a capacitor of two different sizes?
Not sure what you are asking.There are two formulae for working out equivalent capacitance:Two capacitors in parallelThe equivalent single capacitance is the sum of the two capacitors: Ce = C1 + C2Two capacitors in seriesThe equivalent single capacitance is the reciprocal of the sum of the reciprocals of the two capacitors: 1/Ce = 1/C1 + 1/C2⇒ Ce = C1C2/(C1+C2)So you can replace two capacitors by a single one, or a single one by two.
What happens when two capacitors have the same plate separation?
When two capacitors have the same plate separation, the capacitance of the capacitors will be directly proportional to the area of the plates and the permittivity of the material between the plates. This means that the capacitance of the capacitors will be the same if the area of the plates and the permittivity of the material are the same.
How you can produce 240 volts from a single phase 3 wire system with a nominal voltage of 120 volts?
you can use two hot wire different phases with a double pole braker .
How many volts are two 9volts batterys?
Depends on how you connect them together. Connected them in a series and you will have 18 volts. Connected them in parallel and you will still have 9 volts just double the capacity of 1 battery. Click the link to see these 2 connections.
Can you wire 3 6 volt batteries to get 12 volts?
Yes, you can wire three 6-volt batteries in series to achieve a total voltage of 18 volts, not 12 volts. To get 12 volts, you would need to use two 6-volt batteries in series. By connecting the positive terminal of one battery to the negative terminal of the other, you can obtain the desired 12 volts across the remaining terminals.
How do you make a 6 volt battery into a 12 volts?
That is Impossible. You can however make two 6 volt batteries into a 12 volt system by wiring the two 6 volts batteries in Series. You will then have an output voltage of 12 volts but the amperes will only be what one of the batteries have, In other words the volts will double but the amps will stay the same as if you only had 1 battery connected.
Why are capacitors cylindrical?
Capacitors are cylindrical to limit the capacitors physical size. Capacitors are basically two conducting sheets with an insulating sheet between them, this means that the way to make them more compact is to roll them up and hence this gives the cylindrical shape. Another Answer Capacitors are not necessarily cylindrical. Those that are, are manufactured by winding the two plates and the dielectric, swiss-roll style.
