4 + 4 wired in paralell + to + and - to - will give you 2 ohms.

do this on both subs and then wire them together + to + and - to - and that will give you 1 ohm. so now get an amp that is 1 ohm stable 95% of mono block amps are. add your subs rms wattages together not peak let say your subs are 1200 peak and 600 rms then 600 + 600 equals 1200 watts rms is what you need.

so for this instance i would need a 1200 - 1500 watt rms mono block 1 ohm stable amplifier. I like more power just in case after the subs get broke in they want more power.

The function of the bypass diode is to allow the loop current to be measured without disconnecting the current loop connections. It therefore allows for a quick measurement of the loop current without disturbing any control or monitoring equipment that is connected to it.

This is achieved by simply connecting an ammeter across the diode. If the voltage drop across the ammeter is less than that of the diode (about 0.6V) then all of the loop current will flow through the ammeter rather than the diode. The ammeter is therefore able to measure the loop current.

A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.

The components are connected in series (not parallel).

In reverse bias,the currents flowing through the junctioare very smalland interal heating of junction does not takes place

Here's the short version. Grab a seat and buckle up. We see things with our eyes and hear things with our ears. If we could capture these things and broadcast them, we could capture them and could share them with one or many people at some distance from where we are. That's the idea behind television. It's what we see and hear here sent to a remote location - which 'tele' and 'vision' are. If we capture activities with a video camera (using charged coupled devices instead of the "old school" image orthicons), we can turn that action (or the light from it) into an electronic signal. A similar "conversion" is made with the sound, which is captured in a microphone - a device that converts the mechanical energy of sound to electrical energy (an electronic signal). Grab these and combine them, and then run them through a transmitter (modulate a carrier signal) and spit them out to an antenna. We're on air! In a remote location, put up an antenna and direct it toward the transmitter. Connect a television set to the antenna. Turn it on and tune in. The broadcast signal was sent out on a "channel" which has a specific frequency allocation. The receiver in the TV grabs that signal, and it amplifies it. The signals are then demodulated, and the video and audio signals are separated out and sent to other stages for processing. Audio goes to an audio amp and then to the speaker. The video signals are handled by color (red, green and blue), and then "set up" for presentation on a screen. In the "old school" TV with the cathode ray tube (CRT), the electron beams (the cathode rays) "paint" the picture on the screen a line at a time. Further, to avoid "fading" from the top of the picture to the bottom of the picture during one "frame" of that picture, the lines are painted in alternating "fields" of all the odd number lines and then all the even number lines. What's the result? A color picture with sound. Some links are provided for further information.

they are directly proportional and are sometimes used interchangeably..

flux can be insolation , magnetic lines, electrostatic density, pressure...

within a document they generally refer to the same entity if one is electric and one magnetic be careful to sort out which is witch

A good engineer is a person that knows which book to pick up read to get the answers. This is true especially in the electronic field. the branches of electronics is to say immense.

All cells have internal resistance. The value is very small when the cell is fresh. The value increases slightly and slowly as the cell discharges.

So the potential difference across the cell will not noticeably change when a load is initially connected. As the cell becomes more discharged, the drop in potential difference upon connecting a load will increase.

The point at which the cell is no longer any use depends on the minimum voltage which the load requires, and the current required by it.

If the two wires are on a parallel feed you would read the current through the parallel feeders. If the two wires are "hot " to the load and return back from the load the meter will read zero. The two magnetic fields that surround the wires when a current flows through them will cancel each other. As a result of this there will be no magnetic induction induced into the sensing coil of the clamp on meter.

Diodes will have a small leakage current in reverse bias. In most cases, this current can be considered insignificant and ignored.

The impedance of a component (inductor or capacitor) will change with frequency - resistor impedances will not.

Inductor impedance - j*w*L

Capacitor impedance - 1/(j*w*C)

L = inductance, C = capacitance, j = i = imaginary number, w = frequency in radians

The actual inductance and capacitance does not change with frequency, only the impedance.

A: A sampling scope is not real time scope but rather a hi frequency rate of sampling which benefit the observer

A; An ideal op amp should have infinite open loop gain so when the loop is closed with negative feedback it will be stable

Not only on Motorola Portable radio, but in all radio communications:

Frequency is number of cycles (full change circles) per second. When radio device operates on some frequency it requires band of adjacent frequencies to be able to transmit modulation (information) too. To avoid mixing, next transmitter must take some "distance" (higher or lower frequency) far enough from frequency of the first one. According to regulations basic frequencies are "named". Channel number is the name of its frequency given by communication regulations.

For example, TV UHF channel 21 takes all frequencies from 512 to 518 MHz (megahertz), channel 22 from 518 to 524 MHz, and so on...

CB Radio channels 21 and 22 occupy frequencies from CB band, not from TV band. Tables of channel frequencies within various bands can be easily found by search engines.

A joule/coulomb is represented by the volt. Example: a 9v battery provides 9 joules of energy to every coulomb of charge that passes through it.
