Energy Stored in a Capacitor When charging a capacitor, the power supply pushes electrons from the positive to the negative plate It therefore does work on the electrons and electrical energy becom...
The Time Constant The time constant of a capacitor discharging through a resistor is a measure of how long it takes for the capacitor to discharge The definition of the time constant is: The time t...
Capacitors in Series & Parallel Capacitors can be combined in series and parallel circuits The combined capacitance depends on whether the capacitors are connected in series or parallel Capacit...
Dielectric Materials Permittivity is the measure of how easy it is to generate an electric field in a certain material The relativity permittivity εr is sometimes known as the dielectric constant F...
Capacitance Capacitors are electrical devices used to store energy in electronic circuits, commonly for a backup release of energy if the power fails They are in the form of two conductive metal pl...
Capacitors & Diode Bridges 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: ...
Rectification Rectification is defined as: The process of converting alternating current and voltage into direct current and voltage Rectification is used in electronic equipment which requires a...
Investigating Diode Bridges Aim of the Experiment The aim of the experiment is experimentally verify a half-bridge rectifier will produce partial DC output from AC input and a full wave bridge rect...
