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.
That will depend on whether they are added in series or parallel.
If you added more batteries in parallel, then the bulb would shine for a long time. If you added more batteries in series, then the bulb would burn very brightly for a short time and then 'burn out'.
SERIES: A. If the additional battery is added to the circuit in a "Series Aiding" configuration, the bulb would get brighter. However, it would probably burn out very shortly, if not immediately, depending on the power rating of the bulb. Flashlight batteries such as two and three cell flashlights are usually series aiding. B. If the additional battery is added to the circuit in a "Series Opposing" configuration, the intensity of the bulb would decrease or go out completely if the opposing voltages are equal. (you can do a little experiment with a three or four cell flashlight by reversing the polarity of one or more of the batteries. The reversed battery will be series opposing and cancel 1.5 volts of the other batteries.) PARALLEL: If batteries are added to the circuit in parallel, the intensity of the bulb would remain the same but the batteries would last longer. Be sure the battery voltages are the same when adding batteries in parallel.
Depends on if you want a series or parallel circuit. In a series circuit if you wire six 12 volt batteries together you will end up with 72 volts. Wire the same six 12 volt batteries together in parallel and you will still have 12 volts. In a parallel circuit you just wire all positive posts together and all negative posts together. In a series circuit you would wire positive to negative to increase the voltage with each battery added.
The brightness would remain constant but the power draw will increase. If the circuit was series wired, the brightness would go down as you added bulbs.
If you added the batteries in parallel, then the bulb would stay on for a long time and nobody would get any sleep. If you added the batteries in series, then the voltage across the bulb would eventually become excessive and the bulb would burn out.
No it's series circuit.
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.

• In a parallel circuit, there are junctions in the circuit so the current can flow around the circuit in more than one way. • In a series circuit the current decreases as more bulbs are added. •In a parallel circuit, as more bulbs are added, the current increases. • This is because bulbs added in parallel offer less resistance
