4 amperes.
The voltage adds when batteries are connected in series. If they are the same voltage then the voltage doubles. Using Ohm's law: V = I*R with the voltage doubling and resistance being the same you get I = 2V/R and where V/R was your initial current you get I = 2*2ampers = 4 ampreres

When a three light circuit is connected in series with 2 6V batteries what is the voltage across each of the lights?
If a three light circuit is connected in series with two 6V batteries, and the three lights are identical, the voltage across each of the lights is 12V divided by 3, or 4V.
What is the effect of a series circuit?
multiplies source voltage, two 12v dc batteries in series become a 24v circuit; also multiplies resistence
What happens if increase voltage in parallel circuit?
If you keep all of them in series, then each component in your circuit will have more voltage across it and more current through it, and will dissipate more power (heat). If you keep all of the batteries in parallel, then they must all be rated for the same voltage. Nothing about the circuit's performance will change, but it'll be able to operate longer before the batteries die.
How do you check dc voltage... series or parallel?
If you are asking how a voltmeter should be connected in a circuit, then the answer is that it should be connected in parallel with the device across which you want to determine the voltage. This applies whether the circuit is d.c. or a.c.
Four 9-volt batteries are connected in parallel how much voltage is active across the circuit?
Four 9v batteries connected in a parallel will still emit 9 volts because you are not increasing the voltage, you are increasing the life. To increase the voltage of four 9v batteries, you must connect them in a series; that series will emit 9v X 4(batteries), which equals 36 volts.
How must batteries be connected in order to increase the voltage in a circuit?
in series
What is two batteries in a circuit called?
If the batteries are connected from + (positive) to - (negative) then the batteries are connected in "series". If the batteries are AA (1.5v each), then the resulting voltage of the two connected in series will be 3.0v. If the batteries are connected + to + and - to -, then they are connected in "parallel" and for the same batteries the voltage would be 1.5v, but would last twice as long as one battery by itself. A truck battery system is two 12v batteries connected in series (+ to -) to give the truck a running power of 24v.
When a three light circuit is connected in series with 2 6V batteries what is the voltage across each of the lights?
If a three light circuit is connected in series with two 6V batteries, and the three lights are identical, the voltage across each of the lights is 12V divided by 3, or 4V.
How does the voltage of a double battery compare to the voltage of a single battery?
The voltage depends on how the two batteries are connected to one another. If they are connected in a series circuit (positive end to negative end) the voltage will double. If they are wired in a parallel circuit, (It
What happens to the voltage if batteries if they are setup in a parallel and a series circuit?
Assuming all of the individual batteries are the same voltage, if arranged in a parallel circuit the voltage is the same as any one battery. If arranged in a series circuit the voltage will be the sum (the total) of all of the batteries added together.
How are circuits connected when you are using more than one battery?
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.
How many batteries needed in a series circuit?
It depends on the load and desired voltage. The voltage adds as you put batteries in series. Positive to negative, etc.
Can you connect batteries in series and parallel?
Yes, series and parallel connection of batteries is possible. When connected in series Voltage increases. In parallel, Current increases but voltage is constant.
Can Two or more batteries connected in series generate a higher voltage than one alone?
Yes, two or more batteries connected in series can generate a higher voltage than one alone.
How are voltmeters connected to a simple series circuit?
Voltmeters are connected to simple series circuits the same way they are connected to any circuit. They are connected in parallel with the portion of the circuit for which you wish to measure the voltage drop.
What happened to the voltage in the circuit as more dry cells were connected in the series?
The voltage increases in this case.
Why would you add batteries in series?
Putting batteries in series will up the voltage of the entire circuit. Certain things need higher voltage, so you put your batteries in series. Putting batteries in parallel will not up the voltage, but will let the current last longer. Watches would be more of an example for that. You want watch batteries to last long.
