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 17 A current when shorted by a wire of negligible resistance?

R=

Resistance,

Explanation:

Given that,

Voltage of the battery, V = 9 volts

Current produced in the circuit, I = 17 A

We need to find the resistance when shorted by a wire of negligible resistance. It is a case of Ohm's law. The voltage is given by :

So, the resistance in the circuit is 0.529 ohms. Hence, this is the required solution.

0.11 m/s and 0.28 m/s should be correct

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
