Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

How do you measure speaker ohms?
Usually speakers are rated by DC impedance, so you can use a simple multimeter to measure their resistance. Typical values are 4 to 32 ohms.
Yes. DC biasing a transistor is necessary to force it to operate in its' linear region. What you have written is true.

What do substations reduce the voltage for?
A: Substations step down the transmission voltage for distribution for the local area. The reason being that their input is in the range 0f 475 Kv trying to distribute that kind of hi voltage would be totally impractical because of insulation. So a substation step down the hi voltage to a distribution level of 16kv or so.
If voice was to be transmitted at its basic frequency 20-20kc. it will take much time. But by transmitting a very hi frequency media the signal can be there presently. By modulating this frequency by voice and removing the media it can be there instantly.
How does a pull up resistor works?
A pull-up resistor is used to "pull-up" a signal to prevent it from floating or creating an undefined state. Typically a digital input might be looking for a ground or low state to indicate a state. The pull-up resistor is attached to the signal line and to a level which will "pull" the line to a high level in the absense of a low signal. The effect is to provide a reliable hi or lo to an input. The pull up may located close to an input or directly at an output to effect the results. Some eletronic devices have the pull-up devices internally installed.
What is a dumbed down definition of combination circuit?
what is a dumb down definition of acombination circuit
A; occasionally resistors short out especially at hi frequency hi voltage due to external contamination. But usually resistors open up or change to a hi value due to power overstress
What are the three rules for euler circuit path?
An Euler circuit is a path through a graph that visits every edge exactly once and returns to the starting vertex. The three key rules for an Euler circuit are: (1) all vertices with non-zero degree must be connected, (2) every vertex must have an even degree, and (3) the graph must be finite. If these conditions are met, an Euler circuit exists in the graph.
Why is negative voltage given in bently Nevada vibration probe?
be couse it is bantly neveda monopoly used on based of npn transistors
AnswerThere is no such thing as a negative voltage, in the sense you mean -the word you are looking for is negative 'potential'.
What votage will cause an 8 amp current to flow through a 24 ohm resister?
Ohm's law: Voltage equals current times resistance.
8 amperes times 24 ohms equals 192 volts.
Why it is possible to have a wider screen in televisions than in cathode ray oscilloscopes?

When do you kmow that the diode is working?
A diode is working when it allows current to flow in one direction (forward bias) while blocking it in the opposite direction (reverse bias). You can test its functionality using a multimeter set to the diode testing mode; a good diode will show a voltage drop (typically around 0.6 to 0.7 volts for silicon diodes) in one direction and display no conduction in the reverse direction. If it conducts in both directions or shows no conduction at all, it may be faulty.
How-to set swr's on a alpha v-58 ground plain?
Assuming you are setting this for the CB or 10 Meter amateur band. What worked for me, measure around the gamma from the input 7" and use that as a starting point for your gamma match. Do not allow the the wire from the the center conductor of the feedpoint to come into contact with the center section, it should be in free air and in an arc. Extend the vertical sections to their maximum length, shorten in 4 inch incremements until you achieve a 2:1 VSWR on eaither side of the band you matching it to. At this point, drop to 2 inch increments until you achieve a 1.5:1 VSWR on both sides of the band. Adjust the gamma match in half inch increments until you achieve a flat swr. This will take some time and effort but it is worth it. Some things to remember. Antenna is a conductor, IT WILL KILL YOU if you get it into power lines. Have someone help you if at all possible. Close by objects, like power lines, buildings, ladders will throw off your reading. Remember the SWR Trick, If the SWR is Higher on your Highest Frequency and lower on your lowest frequency, then the sections need to be made shorter. And vice versa. Example: Ch:1 is 3:1 CH 40 is 1.5:1 - make it longer. Ch: 1 is 1.0 and CH 40 is 2:1 - make it shorter. Hope this helps. KB5%%%
Control circuits are what type of circuit?
these are circuits that manages tha functioning of the system or in other words are the ones that helps in the proper functioning of the system.
