If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Last month, we clarified the definition of a vector and showed you how vectors are added, subtracted, multiplied, and divided. This month, we'll see how to use vectors in defining a complex circuit ...

Alternating current circuits improve the versatility and usefulness of electric power systems. In the late 1800s, Nikola Tesla demonstrated phenomena with alternating current (AC) electricity that ...

Whether you’re in the lab soldering components or on your laptop running simulations, learning circuits is about blending theory with hands-on practice. RIT’s Circuits Studio Lab offers real-world ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

Spice is a circuit simulator that you should have in your toolbox. While a simulator can’t tell you everything, it will often give you valuable insight into the way your circuit behaves, before you’ve ...
