how battery current flow

[Abdelwakil]

Hi

I know that batteries get constant voltage and variable current , but why (for ex. cell battery) has 5v rating as standard but not 1a std , i mean why the amp change (500mA , 1A , 2A ...) if voltage is always the same ?? (I didn't get that in simulation !)

To answer your question is Current flows from positive to negative

Also the voltage never changes in a parallel circuit and drops in a series circuit

You are charging the battery , so the voltage source is no longer a steady chemical reaction , but actually the AC charging source .
(best not be homework)
If you lower the current does it become steady ?
(Smoothing capacitor getting depleted)
Clues of origin may be in observed frequency of ripple !
