Variable capacitors are no longer as plentiful as they used to be. There was a time when all radio receivers contained at least one, now with the advent of the varicap diode and the frequency ...

Anyone who works with older electronic equipment will before long learn to spot Rifa capacitors, a distinctive yellow-translucent component often used in mains filters, that is notorious for failures.

Tantalum capacitors are constructed using tantalum for at least the anode material.Capacitors in general consist of two polarized conductors separated by an insulating dielectric material. When the ...

A film capacitor's dielectric determines many different attributes about the device, most importantly its rated voltage. Manufacturers are able to increase a capacitor's rated voltage by using thicker ...

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

If a larger value of resistance were used with the same value of capacitance in the above circuit, then a smaller current would flow, therefore it would take longer for the capacitor to charge up ...
