A photoflash unit in a camera is used to discharge a large amount of charge quickly to produce a bright flash of light.
When the flash is triggered, a potential difference of 450 V450\text{ V}450 V is applied across the flash tube.
A charge of 0.15 C0.15\text{ C}0.15 C passes through the flash tube in 5.0 ms5.0\text{ ms}5.0 ms.
Calculate the electrical resistance of the flash tube.
