discharged through a filam? PHOTOGRAPHY: An electronic flash unit for a camera is activated when a capacitor is discharged through a filament of wire. After the flash is triggered, & the capacitor is discharged, the circuit ( see the figure) is connected & the battery pack generates a current to recharge the capacitor. The time it takes for the capacitor to recharge is called the recycle time. For a particular flash unit using a 12-volt battery pack, the charge q, in coulombs, on the capacitor t seconds after recharging has started is given by
q = 0.0009(1-e^(-0.2t))
Find the value that q approaches as t increases without bound & interpret.
q = 0.0009(1-e^(-0.2t))
Find the value that q approaches as t increases without bound & interpret.
