Answer:
The time constant is
Explanation:
From the question we are told that
the time take to charge is
The mathematically representation for voltage potential of a capacitor at different time is
Where is the time constant
is the potential of the capacitor when it is full
So the capacitor potential will be 100% when it is full thus 100% = 1
and from the question we are told that the at the given time the potential of the capacitor is 85% = 0.85 of its final potential so
V = 0.85
Hence
