Sereies, with each cell about 2.2volts
parallel
Both resistors will have the voltage of the battery.
An ammeter must be connected in parallel to the circuit. If you do not understand the difference between parallel and series connection then you should leave it to a competent mechanic/electrician.
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
When batteries are connected in parallel, the voltage remains the same as the voltage of a single battery. This is because the positive terminals are connected together and the negative terminals are connected together, so the voltage across each battery remains constant.
When you have a light bulb in front of each other (all connected to wires to a battery)
If each battery is identical, yes.
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
no..... The battery with lower voltage will consume power from the higher one...
If each lamp is connected in parallel, then there are three 'paths' that draw current from the supply.
