A 2.20 × 10^-6 F capacitor initially at 10 V discharges through 1.40 × 10^6 Ω. Find the time constant and the capacitor voltage and charge at t = 2.16 s.

τ = 3.08 s; V = 4.97 V; Q = 1.09 × 10^-5 C τ = RC = (1.40 × 10^6)(2.20 × 10^-6) = 3.08 s. V = V₀e^(−t/τ) = 10e^(−0.7) = 4.97 V. Q = CV = 1.09 × 10^-5 C.
