Homework Statement Posting here because it was over a previous homework assignment and I don't understand the solution that was given out. For reference, the problem is 2.27 is Griffiths' Introduction to Electrodynamics. It reads "Find the potential on the axis of a uniformly charged solid...

Wow, that was a really dumb mistake on my part. Thanks for helping me though, I probably would have never realized that.

Right. So I have this equation: q(t) = q_oe^\frac {-t} {R_2+R_3} but because R2+R3 is so large in comparison to t=786μs, the e part is approximately 1, and so my calculator outputs nearly the same answer as I had before, which the website counts as incorrect

Also I figured the current go across the switch, so I assumed it would only traverse the right hand side, which is why I use R=R_2+R_3 the equation I originally posted is not what I had written, it was a typo on my part.

Q(∞)? IC = 0 ∴ I1 = I2 Knowing this: Loop for right hand side (I): \frac {q} {C} = I_2R_3 Loop for left hand side (II): V_b = I_2(R_1+R_3+R_4) Therefore, I_2 = \frac {V_b} {R_1+R_3+R_4} plugging this into (I): \frac {q} {C} = \frac {V_bR_3} {R_1+R_3+R_4} then solve for q, which is just...

1. Situation and Variables: A circuit is constructed with four resistors, one capacitor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 30 Ω, R3 = 66 Ω and R4 = 113 Ω. The capacitance is C = 64 μF and the battery voltage is V = 12 V. The positive terminal of the...
