question 269

Multiple Choice

For the circuit shown in the figure, $V = 20 \mathrm {~V} , C = 10 \mu \mathrm { F } , R = 0.80 \mathrm { M } \Omega$ , and the battery is ideal. Initially the switch $\mathrm { S }$ is open and the capacitor is uncharged. The switch is then closed at time $t =$ $0.00 \mathrm {~s}$ . What is the potential difference across the resistor $20 \mathrm {~s}$ after closing the switch?

• A) \(2.3 \mathrm {~V}\)
• B) \(3.0 \mathrm {~V}\)
• C) \(2.0 \mathrm {~V}\)
• D) \(1.6 \mathrm {~V}\)
• E) \(2.6 \mathrm {~V}\)
