A flash unit for a camera has a capacitance of 1500 ?F and resistance of 43 ?. How long will it take the unit to discharge to 40% of its original capacity? (in s)
Homework Answers
The symbols you show in the statement are not shown properly, so
I'll asume the values for "C" and "R" as 1500
and 43
,
respectively.
The equation for discharge in this kind of circuits is:
where 
.
Solving for "t" when Vc=0.4V0:
