Want this question answered?
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
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.
Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
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.
YESAnswerNot necessarily. The current depends on the potential difference and the load resistance. If you connect cells in parallel, you do not effect its voltage or the load, so the current is unaffected (although the battery's current 'capacity' will increase). If you connect the cells in series, then you will increase the voltage and the current will increase.
They are wired in series.
The current in the circuit is(6,000)/(the resistance connected between the terminals of the D cells, in ohms)milliamperes
The voltage increases in this case.
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.
4.5 volts in series; 1.5 volts in parallel.
it explodes if two a series batterys connected in parrallel to another forth circuit , this may result in you changing your pants...
voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same
