Electrolytic capacitors and design rules

This article is in tended t o ex plain the bases about electrolytic capacitor , where t he y are used, basic construction, RLC circuit and much more. This is a fir st article about capacit ors and this article is based on zilsel-invent previous article about low pass filters at the following link : Low pass filter and voltage stabilization Electrolytic capacitors and design rules T he f igure #2 presents already used electrolytic capacitors. As we can see electrolytic capacitor is polarized device which means that it is important to pay attention during capacitor assembling to the PCB (printed circuit board). Depending on the capacitor manufactures, in some cases negative lead is marked with a negative sign , and in some cases positive lead (capacitor pin) is marked with a plus sign . Beside polarization mark, there are also labels about capacitance (for example 470 microfarads ) and maximum allowed voltage (for example 10V). The maximum allowed voltage is important parameter r

Fake VC830L digital multimeter

Image
This article is intended to explain some bad things about cheap digital multimeters since these devices are available in large quantities in Serbia. The key point of this article is security since cheap digital multimeters are not tested/produced according to standards. VC830L is one digital multimeter available in electronics distribution stores in Serbia, but we will avoid company names, since this article is more about “ pay attention before you buy ” cheap digital multimeter. The VC830L is about 10 euros, you cannot expect too much, but if you are not able to buy professional digital multimeter which costs over 100 euros, you will certainly buy the cheap one. Front mask: VC830L digital multimeter. The part interested for us is security so let see what we actually have regarding VC830L digital multimeter. It has three input connectors, starting from the left side: we have connector for 10 amps, common connector (COM) and the right one intended for voltage, r

How to design LM324 Astable Multivibrator

Image
This blog post is intended to describe how astable multivibrator works based on LM324 operational amplifier, RC timer and positive voltage divider circuits. This is one way to implement astable multivibrator since additional options are available like: specialized signal generators or 555 timer integrated circuit configured to work as an astable multivibrator . There are two states related to astable multivibrator based on RC timer or an analog timer (there is also a digital timer integrated into the microcontroller for example, but in general, digital timers are based on astable multivibrators implemented with quartz or resonator external oscillators, since digital timers count PWM /clock oscilations . Anyway, there are different types of astable multivibrators in order to provide clock cycles): charging and discharging. Charging   To describe charging state we will start from beginning with the completely discharged capacitor C (it has zero volts between p
