Batteries have different volts because of several reasons. First they differ in size, the bigger the size the more electricity they can store and supply. Second they are made of different types of materials, each type has its own capacity of generating voltage.
<><><>
The output voltage depends on the materials which have been used to make the cell. The cells in a car battery produce an output voltage of around 2 volts. Lithium cells produce around 3 volts.

What is the effect on current through a circuit of steady resistance when the voltage is doubled?
The current will increase and will flow more. If voltage increases, current must increase.
How do you increase current in electromagnet?
1. Increase the strength of the magnetic field. (More field lines to be cut by wire, therefore more voltage induced) 2. Move the magnet - or the wire - more quickly. (More field lines cut per second, therefore more voltage induced) 3. More coils in wire. (A single straight wire moved in a magnetic field will cut the lines once, but a coil of wire will cut the lines twice. More coils, more cutting, more induced voltage).
What happens to the amount of voltage induced by pushing a magnet through loops of wire if the number of loops is doubled?
Also doubled.
What are ways to increase glucose transport?
1. increase the number of glucose carriers2. increase glucose concentration
How does the number of insects that fall into the liquid affect the number of these useful bacteria?
the number of bacteria will increase if they amounts of bugs falling in increases
What happens if you double the number of batteries used in a circuit?
the voltage and current doubles
What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
How does the number of batteries affect the strength of the electromagnet?
The number of batteries affects the strength of the electromagnet by influencing the amount of current flowing through the wire. More batteries can provide a higher voltage and thus increase the current, which in turn strengthens the magnetic field produced by the electromagnet.
How can we increase the strength of an electro magnet?
Increase voltage. Increase the number of windings,
How many car batteries do you need to power your 100 amp home?
You cannot power a home with car batteries. Batteries are DC voltage. Your home operates on AC voltage. You could use a converter but the number of batteries required to operate an average home would be enormous.
If a circuit has two AA alkaline batteries how many joules of energy does each coulomb of charge?
You need to multiply the number of coulombs by the number of volts. If the two batteries are in series, then you can add the voltage of both batteries.
What happens to the current if the number of bulbs stays the same but you use more cells?
If you add more cells in series with the bulbs, the current will increase as the voltage across the bulbs increases. If you add more cells in parallel with the bulbs, the current will stay the same because the voltage of the cells does not increase when they are added in parallel.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
What happens to the amount of current in a series circuit as the number of batteries increases?
it increases
D cell battery cause electric shock?
No, as D cell battery does not have enough power to shock you. *edit D Cell batteries don't have enough VOLTAGE to shock you. They have plenty of power (Power = Voltage*Current) to shock you, but first you'd have to use a circuit to increase their voltage to thousands of volts. This would decrease their current proportionally and keep the power level the same. Car batteries for example have tremendous amounts of power, but it's in the form of massive amounts of current (number of electrons flowing), the Voltage (intensity of the electrons) is only 12 Volts, which is still safe.
1998 Chevrolet Lumina having serious problems with batteries and had to replace them a number of times.?
have alternator been checked for voltage output
Can you describe how batteries are sources of voltage?
The number of cells in a battery determine the battery's voltage. Different types of batteries have different cell voltages. The cell voltage is dependant on the reactive metals used. A typical car battery will have six cells. Because a typical cell voltage has a source voltage of approximately 2.0 volts, this makes a car battery produce a voltage of 12 volts.
