Document Summary
In a circuit with just a battery and capacitor, the capacitor was charged instantaneously. Adding a resistor will limit the rate at which charge will flow to the capacitor (and the rate that the capacitor voltage will reach the battery voltage) (prelecture question) charge flows from the positive (top) terminal of the battery to the top plate of the capacitor. Since the battery has to remain neutral at all times, exactly the same amount of charge is pulled from the bottom plate of the capacitor and into the negative (bottom) terminal of the battery. No charge flows to the capacitor (q = i = 0) t = 0 (circuit is switch closed to position a) A positive charge is generated on the top plate and a negative charge is generated on the bottom plate. T q c b. Obtained from kirchhoff"s voltage rule: cw (starting at a) ri + q (t) C v b = 0 dq + 1.
