The usual rule for charging a flooded lead-acid battery is that the charge current should be less than 20 - 25% of the Ah rating. for your 4 Ah (4000 mAh) battery,. that would mean a maximum charge rate of about 1 Amp. Gel and AGM batteries can accept a higher charge rate. I don't think there is a minimum charge rate, but the lower the charging current, ...

The answer is kinda. The current will "flow" through the capacitor and go through the resistor. What is happening is that as the capacitor is getting charged, the charge in the capacitor is displaced by the incoming electrons so it comes out the capacitor and flows through. For better detail, you should read this answer I found on Quora.

2.5A is too high, charge current is 1925mA with 4.2V. A charger should stop and alarm for high temperatures, does yours? When batteries age the internal resistance increases, which will result in more heat when charging/discharging. Going over the specification of the manufacturer is risky, especially when you do not keep track of the battery age with a ...

If for any reason, i want to make a resistor have a positive and negative charge on its either ends, what would be the approach for this? Break the resistor somewhere in the middle and position the parts very close together but not touching. You now have a very small capacitor with an equivalent series resistance of the R value. Can a diode be turned ...

This question involves the capacitor paradoxon, where some part of the energy stored in both capacitors seems to disappear. In theory, i.e. in the case of ideal capacitors, without resistances or inductivities or radiation of HF or other losses involved, the capacitors are strictly parallel after connection, which is a contradiction, since the initial ...
