The voltage across the capacitor can be calculated as part of a loop analysis, ensuring that the sum of potential drops (voltage across resistors) and rises (supply voltage) equals zero within a closed circuit loop.
1. Note from Equation.(4) that when the voltage across a capacitor is not changing with time (i.e., dc voltage), the current through the capacitor is zero. Thus, A capacitor is an open circuit to dc. However, if a battery (dc voltage) is connected across a capacitor, the capacitor charges. 2. The voltage on the capacitor must be continuous.
The amount of charge (Q) a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size.
