일반물리학 2 — Circuits: Problem 40

40 In an RC series circuit, emf \(\mathcal{E} = 12.0 \text{ V}\), resistance \(R = 1.40 \text{ M}\Omega\), and capacitance \(C = 2.70 \text{ \mu F}\). (a) Calculate the time constant. (b) Find the maximum charge that will appear on the capacitor during charging. (c) How long does it take for the charge to build up to \(16.0 \text{ \mu C}\)?
