What are ac circuits?

Some articles on ac circuits, circuit, ac, circuits:

Electrical Resistance And Conductance - AC Circuits - Frequency Dependence of Resistance
... Another complication of AC circuits is that the resistance and conductance can be frequency-dependent ...
Capacitator - Theory of Operation - AC Circuits
... from a spectrum of frequencies, whence the circuit's reaction to the various frequencies may be found ... The - j phase indicates that the AC voltage V = Z I lags the AC current by 90° the positive current phase corresponds to increasing voltage as the capacitor charges zero current ... capacitor results in a lower voltage amplitude per current amplitude—an AC "short circuit" or AC coupling ...
Transmission Tower - Towers For Different Types of Currents
... It is possible to install circuits for different types of current on the same tower ... In principle, it is possible to install AC circuits of different frequency and phase-count or AC and DC circuits on the same pylon ... Usually all circuits of such lines have voltages of 50 kV and more ...

Famous quotes containing the word circuits:

    The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower.
    Robert M. Pirsig (b. 1928)
