# CAPACITORS ## Capacitors in Series calculations

In this post we will be looking at Capacitors in series calculations. Capacitors in series are connected end to end so that the same charge (Q) appears across each of them. Meanwhile, in this connection, different potential difference (Pd) appears across each of the capacitors. The sum of voltage drops across each of the capacitor … ## Capacitor number code

The post “capacitor number code” lists Non Polarized capacitors number codes with their values in Pico Farad (pF), Nano Farad (nF), and Micro Farad (µF) respectively. Also, it teaches you how to calculate the value by yourself for knowledge sake. This is because you may not be close or in position of the number codes …

## THE TYPES OF CAPACITOR

There are many different types of Capacitor. In general, they fall under one of these categories: Polarized Capacitor Non-Polarized Capacitor Variable Capacitor POLARIZED CAPACITORS Polarized capacitor types of capacitor must be connected correct way otherwise, will be damaged if connected wrongly. At least one of their leads (terminals) is mark either “+” or “−”.  Examples …

## Capacitors in Series and Parallel Calculations

Capacitors also like resistors can be connected either in series, parallel, and or combinations of both. Their calculations are opposite to that of Resistors. That is; if they are in series, they will be treat as resistors in parallel and vice –versa. In this article, we will consider capacitors in series and parallel calculations. CAPACITORS … ## Parallel Capacitors Calculations

Let’s see parallel capacitors calculations. Capacitors connected in parallel are connected side by side and their terminals joined together so that the same applied potential difference (Pd) appears across each of them but each has a different magnitude of charge (Q) across it. The figure below shows three capacitors connected in parallel. The same potential … ## VARIABLE CAPACITORS

Variable capacitors are mostly use in radio tuning circuits and sometimes called “tuning capacitors”. They have very small capacitance values, typically between 100pF and 500pF. Many of them have short spindles, which are not suitable for the standard knobs use for variable resistors and rotary switches. Variable capacitors are not use in timing circuits because … ## Non Polarized Capacitors

These are value capacitors and they are not polarized. Non polarized capacitors they can be connected either way round. They are not damaged by heat when soldering, except for one unusual type (polystyrene). They have high voltage ratings of at least 50V, usually 250V and so on. It can be difficult to find their values … ## Polarized Capacitors

Polarized capacitors must be connect correct way otherwise, will be damage if connected wrongly. At least one of their leads (terminals) is mark either “+” or “−”.  Examples of these capacitors are (with brief descriptions): Electrolytic capacitor Electrolytic capacitors may be found in these two different forms; AXIAL (where the leads are built to each …
