Power supplies typically provide stable DC voltages (though some can supply AC), can deliver high currents, and are designed for regulated output, unlike portable batteries that may vary in voltage as they discharge.

I think the power supply is what we get in our home from electric cooperation and Battery is a static form of energy which is used in TV remote.

Can anyone please explain the difference between power supply and battery?

Power supply may be ac or DC. But battery always DC.

A power supply, such as those in a computer take the power supplied by the wall outlet and split it into the various forms that your computer hardware needs to operate.

A battery has a set amount of power stored inside it which is constantly being drained (or replenished if rechargeable).

However the voltage received from power supply is AC and from battery is DC so I recommend that option A is correct.

Actually voltage is a force which tend to move the current (electrons) and current is flow of electrons.

Power suppuly may be different type

1. variable
2.constant
3.AC type
4.DC type

Battery work in limited or fixed time but power supply may be work continue or fixed time.

what can you conclude about the relationship between the voltge and the current from the charactaristic?
