4.4.104 - Capacitor discharge equations

Use Q = Q0e^(−t/RC), I = I0e^(−t/RC), and V = V0e^(−t/RC) for capacitor discharge, and derive and use ln Q = ln Q0 − t/RC, ln I = ln I0 − t/RC, and ln V = ln V0 − t/RC.

Use - capacitor discharge equations to connect the rule to the data and decision in the question.

This matters because - capacitor discharge equations determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - capacitor discharge equations to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
