What is a Capacitor and what is Capacitance

Capacitor Discharge (Voltage over Time)

During the discharge of a capacitor through a resistor, the voltage decreases exponentially over time.

  • Where:*
  • *V(t)* is the voltage at time t (in volts, V)
  • *V_0* is the initial voltage (in volts, V)
  • *R* is the resistance (in ohms, Ω)
  • *C* is the capacitance (in farads, F)
  • *t* is time (in seconds, s)

Capacitor Charging (Voltage over Time)

During charging, the voltage across a capacitor increases exponentially, approaching its final value.

  • Where:*
  • *V(t)* is the voltage at time t (in volts, V)
  • *V_0* is the final voltage (in volts, V)
  • *R* is the resistance (in ohms, Ω)
  • *C* is the capacitance (in farads, F)
  • *t* is time (in seconds, s)
