Solved: The flash unit on a camera operates by storing
Chapter 3, Problem 3.297(choose chapter or problem)
The flash unit on a camera operates by storing charge on a capacitor and releasing it suddenly when the flash is set off. The following data describe the charge remaining on the capacitor (measured in microcoulombs, +C) at time (measured in seconds). (a) Use a graphing calculator or computer to find an exponential model for the charge. (b) The derivative represents the electric current (measured in microamperes, +A) flowing from the capacitor to the flash bulb. Use part (a) to estimate the current when s. Compare with the result of Example 2 in Section 2.1.
