question 104

Multiple Choice

An uncharged capacitor and a resistor are connected in series to a battery as shown. If $\varepsilon$ = 15 V,C = 20 $\mu$ F,and R = 4.0 $\times$ 10⁵ $\Omega$ ,the charge on the capacitor as a function of time is

• A)Q(t)= 600 (1 - e^-0.125t)\(\mu\)C
• B)Q(t)= 300 (1 - e^-0.250t)\(\mu\)C
• C)Q(t)= 300 (1 - e^-0.125t)\(\mu\)C
• D)Q(t)= 600 (1 - e^-0.250t)\(\mu\)C
• E)Q(t)= 150 (1 - e^-0.750t)\(\mu\)C
