1.
In the circuit shown here. R1 = 1.00 MΩ, R2 = 2.00 MΩ, and C = 1.00μF.
The capacitor is initially without charge on either plate.
At t = 0, switch S is closed, and t = 2.00 s, switch S is opened.
(60%)
(a) Sketch a graph of the circuit in R2 between t = 0 and t = 10.0 s.
(b) Find the voltage across the capacitor at t = 8.00 s.
(c) 畫出自 t = 0 至 t = 10.0 s 過程中,
電路上自 t = 0 起所消耗之總熱能隨時間 t 的變化。
