A good point, but no-one's claiming a single battery would produce yield 5 AHrs (or even pass such a charge, which is not the same as yielding), or that a real AA would happily provide 7.5 amps.
In reality the depleted battery would probably break the circuit. Implicitly I understood these...
Now let's say I have four AA batteries each 2.5 amp hours.
First scenario:
One battery is connected behind three batteries in parallel.
Now I would guess then the current of the battery behind would be three times that of each of the ones in parallel.
Correct.
So for the first...
Amp hour is measure of charge (e.g. useful electrons) in battery. Energy in battery is voltage * charge.
consider,
power, P = V x I
energy, E=P x time = V x I x time = V x Amp Hours
Each battery has fixed voltage and total charge, regardless of configuration, so total energy is not...
Hi,
I'm wondering how to drive front and rear lights off one dynamo. See diagram for current setup.
Lights are hooked up to dynamo in parallel.
The LM7805 and LM317 are voltage regulators which drop the voltage from 12v to 5v and 10v respectively.
Currently only the headlight works, the...
