It should be noted that the reactance of C ac is normally much higher than that of the power recipient circuit, and as such, the power supply behaves as if it is a constant current source. This type ...

The Basics of Vector Analysis Part 1 The Basics of Vector Analysis Part 3 The Basics of Vector Analysis Part 4 Last month, we clarified the definition of a vector and showed you how vectors are added, ...

Of special value to us is the effective AC circuit resistance at some specific frequency, called inductive reactance, expressed in ohms. Inductive reactance is found by the formula XL=2ΠfL.

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed.

Calculations of power and energy are relatively straightforward when the subject is strictly dc circuits. The situation is more complex in the ac world, however. Here are the ...

However, this rarely happens and only in alternating current (AC) circuits containing pure resistances. Most AC circuits contain some type of inductance, in which case the current waveform lags the ...

Each must withstand the circuit voltage that the original .0015 did, but the RF current is divided between the two. The .001 mfd will handle two-thirds of the RF current in amperes. The .0005 ...
