Homework Statement
A 12.8 micro-F capacitor is connected through a 0.890 M-ohm resistor to a constant potential difference of 60.0 v.
Homework Equations
q=CE(1-e^(-t/(RC))
i=(E/R)-(q/(RC))
The Attempt at a Solution
Compute the charge on the capacitor at the following times after the connections are made: 0 s, 5.0 s, 10.0 s, 20.0 s, and 100.0 s.
Solved for q and according to masteringphysics (the homework program we use) I got all the q values correct. Here they are:
0 , 2.7e−4 , 4.5e−4 , 6.4e−4 , 7.7e−4
Second part, and this is the part that I need help on. I think I'm right but the program says I'm incorrect on the fourth term
Compute the charging currents at the same instants. Calculated i:
6.74e-5 , 4.37e-5 , 2.79e-5 , 1.12e-5 , -1.76e-7
It says "Term 4: Very close. Check the rounding and number of significant figures in your final answer."
What am I doing wrong?
Thanks!
