Smoothing | CIE A Level Physics Revision Notes 2022

In rectification, to produce a steady direct current or voltage from an alternating current or voltage, a smoothing capacitor is necessary; Smoothing is defined as: The reduction in the variation of the output voltage or current. This works in the following ways: A single capacitor with capacitance C is connected in parallel with a load resistor of resistance R

AC Capacitor Circuits | Reactance and Impedance—Capacitive

Capacitive reactance is the opposition that a capacitor offers to alternating current due to its phase-shifted storage and release of energy in its electric field. Reactance is symbolized by the capital letter "X" and is measured in ohms just like resistance (R).

Introduction to Capacitors, Capacitance and Charge

However, when a capacitor is connected to an alternating current or AC circuit, the flow of the current appears to pass straight through the capacitor with little or no resistance. There are two types of electrical charge, a positive charge in the form of Protons and a negative charge in the form of Electrons. When a DC voltage is placed across a capacitor, the positive (+ve) charge

What is the Role of Capacitor in AC and DC Circuit?

Role of Capacitor in AC Circuits: In an AC circuit, capacitor reverses its charges as the current alternates and produces a lagging voltage (in other words, capacitor provides leading current in AC circuits and networks) Role of Capacitor in DC Circuits: In a DC Circuit, the capacitor once charged with the applied voltage acts as an open switch.
