8.2: Capacitance and Capacitors
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.
Reservoir Capacitor
When the supply is first switched on the voltage across the capacitor is zero (at t 0).During the first half of the first positive half cycle (t 0 to t 1) the capacitor charges up to the peak value of v i, V i.As the input voltage passes its peak value (at t 1) it becomes lower than the voltage across the capacitor, so the diode becomes reverse biased and stops conducting.
Capacitor in Electronics
Capacitance Capacitance is a capacitor''s ability for storing an electric charge per unit of voltage across its plates. The formula for capacitance is: 𝐶=𝑄 / 𝑉 where: 𝐶 is the capacitance in farads (F), 𝑄 is the charge in coulombs (C), 𝑉 is the voltage in volts (V).
