Resistance and reactance collected by bioelectrical impedance (BIA) can be used in equations to estimate percent body fat at relatively low cost and subject burden. To our knowledge, no such equations ...

It used to be a major rite of passage for a hardware hacker to acquire an oscilloscope. Until recently, new instruments were rarely in normal people’s budgets, so you probably made do with a used ...

This tutorial will showcase how inductance, capacitance and resistance affect alternating current. A circuit may have the alternating current through it and the voltage across it rising and failing ...

Inductive Reactance is defined as the opposition to current flow. It is the reaction of the inductor to the changing value of alternating current. To explain further, a back electromotive force (emf) ...

Variable current will generate inductance, capacitance, and their related properties of inductive and capacitive reactance. Although there's no energy loss that directly results from these properties, ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

This month we take a more in depth look at the tee network. This impedance matching network, aptly named, has the appearance of a T. The vast majority of AM transmission facilities will have at least ...

When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...
