Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

I learned some basic electronics in high school physics class: resistors, capacitors, Kirchhoff’s law and such, and added only what was required for projects as I did them. Then around 15 years ago I ...

In Part 1 of the Electronics for Kids series, we looked at LEDs; in Part 2, we explored capacitors; and in Part 3, we took an in-depth look at electrical measurements. In this article, we will focus ...

A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
