An ideal battery would produce an extraordinarily large
Chapter 27, Problem 27.69(choose chapter or problem)
An ideal battery would produce an extraordinarily large current if shorted by connecting the positive and negative terminals with a short wire of very low resistance. Real batteries do not. The current of a real battery is limited by the fact that the battery itself has resistance. What is the resistance of a 9.0 V battery that produces a 21 A current when shorted by a wire of negligible resistance?
