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.

What happens when you add more batterys parallel circuit?

The voltage stays the same but the amp hours capacity increases.


What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?

Well, isn't that just a happy little question! When you add more dry cells to a circuit, the ammeter will show a higher reading because there is more current flowing through the circuit. The voltmeter reading will also increase because the total voltage of the circuit will be higher with the addition of more dry cells. Just remember to always paint with light and electricity in your circuits, my friend!


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.


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.

When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?

When more light bulbs are added in parallel to a circuit, the total resistance of the circuit decreases. This is because in a parallel circuit, the reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances. More paths for current to flow mean less overall resistance in the circuit.
