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.


Is a circuit with 2 batteries and a light bulb a series circuit?

A circuit with two batteries and a light bulb can be a series circuit if the batteries and the light bulb are connected in a single path, meaning the current flows through each component one after the other. In this configuration, the voltage from both batteries adds up, and if one component fails, the entire circuit stops working. However, if the batteries are connected in parallel or if there are multiple paths for current to flow, it would not be considered a series circuit.


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 should batteries be connected to in order to obtain higher voltage?

To obtain a higher voltage, batteries should be connected in series. In a series connection, the positive terminal of one battery is connected to the negative terminal of the next, which allows the voltages of each battery to add together. For example, connecting two 1.5V batteries in series results in a total voltage of 3V. This method increases the overall voltage while maintaining the same capacity (amp-hour rating) as a single battery.


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.

What are the differences between a series and parallel circuit when connecting batteries?

In a series circuit, batteries are connected end-to-end, increasing the total voltage but keeping the same current. In a parallel circuit, batteries are connected side-by-side, keeping the same voltage but increasing the total current.


How can two batteries be connected in series to create a circuit?

To connect two batteries in series, you would connect the positive terminal of one battery to the negative terminal of the other battery. This creates a circuit where the voltage of the batteries adds up, providing a higher total voltage for the circuit.


What is the voltage in a series circuit where multiple components are connected in a series, known as series circuit voltage?

In a series circuit, the voltage is the same across all components connected in a series. This is known as the series circuit voltage.


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.

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 are the differences between a parallel and series circuit when it comes to connecting batteries?

In a parallel circuit, batteries are connected side by side, allowing each battery to provide power independently. In a series circuit, batteries are connected end to end, increasing the total voltage but requiring all batteries to work together to provide power.

Does the series connection of batteries double the voltage?

No, the series connection of batteries does not double the voltage. The voltage increases with each additional battery connected in series.


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.
