Question

The electric current I (in mA) for a particular RC circuit is given by
i=0.8(10-e^-0.15) where t is the time (in s).
Evaluate i for t=4.667 s.

Answer 1

You should include "t" in the formula if you want a response.

I believe the equation might be:\[i=0.8(10-e ^{-015t}\]
But am just guessing. The formula I have seen for current in a RC circuit is\[i(t)= (E/R)e ^{-t/T}\]Where T is the RC time constant.
