5.10: Exponential Charge Flow
A new electronic element, a capacitor, is introduced. When a capacitor is part of an electronic circuit, exponential decay of current and voltage is observed. Analogies are made between … The voltage across the capacitor for the circuit in Figure 5.10.3 starts at some initial value, (V_{C,0}), decreases exponential with a time constant of (tau=RC), and …
CHARGE AND DISCHARGE OF A CAPACITOR
the resistance. When a charged capacitor is connected to a resistor, the charge flows out of the capacitor and the rate of loss of charge on the capacitor as the charge flows through the resistor is proportional to the voltage, and thus to the total charge present. This can be expressed as : so that (1) R dq dt q C dq dt 1 RC q
