question 99

Multiple Choice

An uncharged capacitor and a resistor are connected in series to a battery at time t = 0 s. If ε = 15 V, C = 20 μF, and R = 4.0 × 10⁵ Ω, the charge on the capacitor as a function of time is

• A) Qt) = 600 1 - e^-0.125t) μC.
• B) Qt) = 300 1 - e^-0.250t) μC.
• C) Qt) = 300 1 - e^-0.125t) μC.
• D) Qt) = 600 1 - e^-0.250t) μC.
• E) Qt) = 150 1 - e^-0.750t) μC.
