There is no answer to this question. It could be anywhere between 2.5V and 12V. If you connected them in series the answer would be 20.5V, in parallel the higher voltage battery will discharge into the lower rated cells, the resultant voltage is dependent upon the internal resistance of each of the batteries. In practice you wouldn't do this, so it's either a mistake or trick question. www.powerinspired.co.uk
When you connect the three batteries together you will have a circuit with current. The final voltage across the connection point(s) will be some value which you can't calculate unless you know the internal resistances of the batteries. If you actually do this you should be carefull because the currents can get quite high, causing vapour pressure in the batteries and possibly cause a battery to explode .
6V, for ideal batteries of course. Be careful though as some real types of battery do not tolerate being connected in parallel and can burst, catch fire, or even explode.
Total voltage output of 5 2v cells connected in series would be 10v
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same
All batteries connected in series have additive voltages. All same voltage batteries connected in parallel have the same voltage as one of the parallel battery but their amp hour capacity is increased. Example series wound batteries of four 1.5v batteries, would lite a big 6v flashlight. (all 1.5v batteries = Et= 1.5v x4=6volts). That is the big square battery to lite square flashlights.
When two identical 3v batteries are connected in series with the negative terminal of one of them in contact with the positive terminal of the other the total voltage of the combination is 6v.
The batteries can be connected in parallel or in series. In parallel, good batteries of the same voltage will have a total voltage across them equal to the voltage across one of them. Those batteries in series will have a total voltage equal to the sum of the voltage of each of the batteries.
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
If the 2nd battery is connected "in series" with the 1st battery, the voltage will increase & the motor will run faster. If the 2nd battery is connected "in parallel" with the 1st battery, the voltage will not change, but the total battery capacity will be greater & therefore battery life will be longer than when using just 1 battery.
When placing voltage sources in parallel, the total voltage is the same as the individual battery's voltages. For example: If I was to place 4 "AA" 1.5 volt batteries in parallel with a life of x hours, the out put would be 1.5 volts with a life of 4x hours. note: never place batteries in parallel that are not in the same condition (charge, voltage, ect...).

4.5 volts in series; 1.5 volts in parallel.
7.5 Volts
Sources with different voltages should never be connected in parallel, you would have a difference of potential. Any time you have a difference of potential connected together you will have sparks, which could cause the batteries to explode.

10 volts. The formula to work that out is: quantity of cells*voltage of cells
