8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …
Does Voltage Change Across a Capacitor?
Mathematically, the voltage across the charging capacitor (Vc) at any given time (t) can be expressed by the formula: Vc(t) = Vsource * (1 – e^(-t/τ)) Where: Vc(t) is the voltage across the capacitor at time t Vsource is the …
