If the cells are added in series, then the terminal voltage will increase, as would the internal resistance. If they are added in parallel, then the voltage would remain the same as for one cell, but the internal resistance would fall, and the available charge (in ampere hours) would increase.

When you add a second battery to a series circuit what happens?
Adding a seound battery to a series circuit will increase the voltage, and require less current to keep the lights (if there are any on) as bright. Say you have a 6v battery, then you add another 6v battery. the voltage of the circuit would be 12v
Does voltage add in a series circuit?
The voltage between the ends of the circuit doesn't change ... that's where the power source is connected. But when you add more items in a series circuit, the voltage across each item changes. The individual voltages across each item in the series circuit always add up to the voltage of the power source. So in general, if you add more items, the voltage across each of the original ones must drop somewhat.
What could you add to the circuit to control the bulb?
Switch
As you add more lamps to a parallel circuit what will the ammeter reading do?
If the amp meter is in series ahead of the first parallel branch of lamps the meter will read an increase in current.
How can you make a current smaller in a circuit?
Taking some bulbs out of the circuit!! (I think :P) Taking some bulbs out of the circuit!! (I think :P) Use Ohm's law I = E/R. Add some values and check it out. You use the formula V = IR (where V and E are the same thing, voltage. I is the current. R is the resistance). If you add more resistance then your current will be lower. I would suggest looking at parallel and series resistance so that you can understand equivalent resistance.
What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?
Assuming you add more cells in series, the voltage will increase. If you don't change the resistance of the circuit, this in turn will also increase the current.
What happens when you add more batterys parallel circuit?
The voltage stays the same but the amp hours capacity increases.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
When two cells with the same voltage are connected in a series circuit what happens to the voltage?
There is addition of voltage. Dry cells have 1.5 volts irrespective of there size. if the cells are added as same polarity in series it will add if are parallel then voltage remains same
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 in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?
"http://www.tpub.com/neets/book1/chapter3/1-26.htm" This site explains how to calculate the resistance, but it decreases the resistance when you add more.
What happens if you add more loads to a series circuit?
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
What happens if you add more batteries to a circuit?
Depends on how you add them. Added in series, the voltage will increase, maybe to the point of damaging the LED. If the LED survives, it will shine brighter. Added in parallell, the LED will shine the same, and will be able to shine longer before draining the batteries.

If you have a circuit with one battery What happens to the voltage and amperage when you add another battery plus side to minus side to the circuit?
