Let''s suppose the forward voltage of the diode is 0.3V. While the capacitor is charging, the voltage at the point on the bottom of C1 (let''s call this node Vc-) is held at 2.7V, and so the capacitor charges to (4-2.7) = 1.3V. When V2 shuts off, the voltage at Vc- is still 2.7V but V2 = 0, so the diode is in reverse bias and no current flows

6 Frequently Asked Questions about “Capacitor adjusts voltage”
How does voltage affect current across a capacitor?
The current across a capacitor is equal to the capacitance of the capacitor multiplied by the derivative (or change) in the voltage across the capacitor. As the voltage across the capacitor increases, the current increases. As the voltage being built up across the capacitor decreases, the current decreases.
Does a capacitor resist a change in voltage?
In other words, capacitors tend to resist changes in voltage drop. When the voltage across a capacitor is increased or decreased, the capacitor “resists” the change by drawing current from or supplying current to the source of the voltage change, in opposition to the change." "Resists" may be an unfortunate choice of word.
How do you calculate voltage in a capacitor?
Thus, you see in the equationt that V C is V IN - V IN times the exponential function to the power of time and the RC constant. Basically, the more time that elapses the greater the value of the e function and, thus, the more voltage that builds across the capacitor.
Why is the voltage of a capacitor important?
That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short.
What happens if a capacitor is added to a resistor?
We now apply a voltage of 5V to the circuit (like a step increase - instantaneously). The voltage across the resistor changes instantaneously to 5V. If a capacitor is introduced into this circuit, it will gradually charge until the the voltage across it is also approximately 5V, and the current in this circuit will become zero.
Why does a capacitor voltage remain at VP?
The capacitor voltage remains at Vp because the open diode prevents the capacitor from discharging. The output voltage is now the constant capacitor voltage in series with the input voltage, i.e., Figure 3.8. These circuits clamp the peak of the input voltage at (a) zero, (b) + V, and (c) − V.
