When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

The capacitor meter presented here can measure capacities between 100pF and 1uF on five areas of measurement, more we can say multimeter or tester. Circuit consists of an oscillator with variable ...

This LC meter circuit can measure coils and capacitors. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter ...

If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

What causes the degradation of aluminum electrolytic capacitors in power-supply designs? What is ripple current and how can it influence capacitors in power-conversion circuits? Step-by-step ...

Robustness in a power-supply design is based on predictable, long-term service life. In conventional switch-mode power supplies (SMPS), this is most often dictated by the characteristics of aluminum ...
