**Q1:** I have a battery, say 15 AH and I have a load which consumes 1.5Amps; How does this used to see the capacity of a battery? If the battery is able to deliver 15 AH of capacity that means will it die/discharged in 10 seconds if I put a 1.5 Amps load on it since load is taking 1.5 Amps from battery every second or does it mean it will die/discharged in 10 hours? Is the rating on battery tells us the discharging rate in hours or seconds?
**Another question:** What will happen if I connect the AC terminals to battery? I know it won’t charge but will it explode or something like that? Is it dangerous for us/battery to do this thing? If I have a line wire from which both AC and DC are passing through and now I connect the battery with it, will it be able to filter its DC component from wire itself (and charge itself) or do I have to make a filter(rectifier) for it to separate DC 1st and then charge the battery?
**Q3:** What will happen if I use the neutral wire to carry both the DC + AC line? Should I use a thicker wire? Will it cause some different oscillations in the wire? Is it bad for the AC line?

Q1: The rating on a battery, such as 15AH, indicates the total energy capacity it has. It means that the battery can deliver 1.5 amps for 10 hours before it gets depleted. So if you use a load that consumes 1.5 amps, the battery will last for 10 hours before it needs to be recharged. Conversely, if you use a higher load, the battery will discharge more quickly.
Q2: Connecting the AC terminals to a battery can be dangerous because it may cause a short circuit, which can lead to overheating, fire, or explosion. The AC voltage can vary depending on the source, so it may damage the battery or cause it to leak. Connecting a battery to a wire that carries both AC and DC may not charge the battery because the AC current will not be converted to DC, but it may cause electrical interference or noise.
Q3: It is not advisable to use the neutral wire to carry both DC and AC, as it may cause electrical problems. The neutral wire is designed to carry only AC current and it may not be able to handle the DC component. It could also cause interference or noise in the wire and affect other devices or appliances connected to the same circuit. It is recommended to use a separate wire for DC current or to use a transformer to convert the AC voltage to DC.
