I have the first one down but 2-4 I need help with
Participation Activity 12 1) Solve for x in the equation ex=2 2) Solve for x in the equation In(x) = 3 3) Express the equations for the charge on the capacitor (q(t)) and the current through the resistor (i(t)) when the capacitor is being charged by a source of potential difference. Briefly sketch the charge vs. time graph and the current vs. time graph. 4) Express the equations for the charge on the capacitor (q(t)) and the current through the resistor (i(t)) when the capacitor is being discharged and is acting as the source of potential difference in the circuit. Briefly sketch the charge vs. time graph and the current vs. time graph.
