Question 132

A photographic flash unit uses a 450 μF450\ \mu\text{F}450 μF capacitor to store 9.0 J of electrical energy. To trigger the flash, the capacitor is discharged through a xenon tube with an effective resistance of 8.0 Ω.

What is the maximum current through the xenon tube during discharge?
