Sounds reasonable. Are you possibly also supposed to make an observation about the properties of the resulting battery pair?CasterlyRock said:I quess that nothing happens because there is no voltage difference.
I meant properties of the pair after connection compared to a single battery. Volts? Amps? Amp-hour capacity?CasterlyRock said:No, it only says that batteries are the same.
Really nothing except what I wrote. The question has a conceptual nature. I assumed that when connected, batteries are in parallel, that means the same potential as it was, so nothing changes.insightful said:I meant properties of the pair after connection compared to a single battery. Volts? Amps? Amp-hour capacity?
I don't understand. Do you mean if I would apply a resistor to that new one battery (lets say a resistor is a lightbulb) it would shine brighter than one applied to the original battery?insightful said:Could you not say that you produced a "new" battery with the same volts, but twice the amp and amp-hour capacity?
Why would it shine brighter with the same volts applied?CasterlyRock said:I don't understand. Do you mean if I would apply a resistor to that new one battery (lets say a resistor is a lightbulb) it would shine brighter than one applied to the original battery?
No, I said the amp capacity is greater than before. How much greater?CasterlyRock said:P=I^2*R. You've said that amp is greater than before.
The purpose of connecting two batteries + with +, - with - is to increase the voltage output. When connected in series, the voltage of the two batteries adds up, resulting in a higher voltage output.
No, connecting two batteries + with +, - with - will not increase the battery life. The battery life is determined by the capacity of the individual batteries and connecting them in series does not change this.
Yes, it is safe to connect two batteries + with +, - with -. However, it is important to make sure the batteries have the same voltage and are connected properly to avoid any short circuits or damage to the batteries.
Yes, you can connect more than two batteries + with +, - with -. The voltage output will increase with each additional battery added in series.
If you connect two batteries + with +, - with - and they have different voltages, the battery with the higher voltage will discharge into the battery with the lower voltage. This can cause damage to the batteries and should be avoided.
