Crossover Lesson 83
A crossover is basically a filter
consisting of coils and capacitors non-polarized.
L = COIL: This lets pass only low frequencies or low notes.
C = CAPACITOR: This lets through high frequencies or notes.
The left figure is an
example of a crossover of two simple ways. For the development of a
splitter for speakers of 4 and 8 ohms, the form (formwork which is
wound) coil air-core will have an inch in diameter and one inch long.

Volts peak to peak Lesson 82
We have heard countless
times the voltage peak to peak, meaning?. Then we will explain.
The peak to peak voltage is not simply the sum of the two maximum amplitudes of the alternating current, the sense of direct and inverse.
Because the peak voltage has a very short duration, it has enough power for most applications. We then speak of an average amplitude level, in other words volts RMS, which is equivalent to the size it should have a continuous electrical current to perform the same work of resistive, inductive and capacitive not as a resistance heating oven or, light a bulb.
