How do you check MOSFET transistor using analoge multitester?
A VOM will never do it. A curve tracer Will check all the parameters. Actually that goes for any other component you want to test.
What color are capacitors on a motherboard?
red (rare), metallic green, blue, light blue, brown, lime green, yellow, silver, black, gray, purple (rare).
A zener diode, a transistor, a rectifier diode, and a few resistors. A 10.5V zener diode will conduct until the voltage across it drops to below 10.5. If the relay is small enough, a zener diode is all you need. However, more than likely the current draw of the coil would burn the zener out. Use the zener to drive a transistor, and use the transistor to trigger the relay. V+ | |_______________________ | | _|_| _____|___ |/ \ 10.5V | | /___\ | 3 Relay | __|__ 3 Coil | / \ 3 0---------- /___\ 3 | | | 3 \ \ 4.7K | | / 2.2K / |____ ___| \ \ | / / | | | B | / C | |________|/ | |\ 2N2222 | | \ | | E |______________________| | _|_ \\\ When the voltage is above 10.5V the zener will conduct ant turn on the transistor. The transistor will power the relay. When the voltage drops below 10.5V the zener will stop conducting, shutting off the relay. The rectifier diode absorbs transients caused by the field breakdown in the coil, protecting the transistor. Just a plain resistor will do it or you may follows suggestion and use a computer to do that. The last time i used those ancient devices i find out they operate as a current device like minimum pull in current source. So a passive resistor in series will insure the minimum pull in source however it could be higher then the 10.5 v you need.The above designi just plain silly.
How do you change the hall effect switch in a 93 cadillac deville 4.9L?
It is magnetic pick-up in the bottom of distributor. If car has alot of miles on engine, best to get a rebuilt distibutor. Otherwise, use a technition to replace pick-up. Have to disassmble distibutor to access pick-up.
A parallel circuit is one which the current passes through the electrical devices in separate paths.
For example, consider 2 resistors (loads):
A practical example
In a house each lamp and its light switch are wired in series with each other but all the separate circuits feeding the lights in a house are wired in parallel with each other because any one light can be either on or off independently of the others.
a parallel circuit is when electricity flows through more than one pathway
Can you list two reasons that modulation is used for communications transmissions?
To send multiple messages by changing the carrier signal.
To be able to use smaller antennas higher frequency means smaller antenna
Are led lights dangerous if place in a wooden box?
Sometimes it is but depends how hot the light gets.
What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
Why does memory access take more machine cycle than register access?
Because of different in speeds of cpu the system bus and the memory circut
What are the uses of silicon oxide in a mobile phone?
As in all modern electronic devices, a microscopically thin layer of silicon dioxide is grown as an insulator and passivator over the silicon of integrated circuits and discrete transistors. This process was developed in 1959 by Fairchild Semiconductor for use in their Planar Process for making silicon transistors and immediately spread throughout the industry, permitting use of inexpensive plastic packaging for semiconductor devices for the first time.
Silicon oxide polymers are also in the silicone rubber parts that seal the case and keyboard from moisture.
Where can someone buy 4 channel amplifier?
One can purchase a 4 channel amplifier from any local music supply store as well as some local department stores. One can also purchase these from online retailers such as Amazon.
If 5 miliamps were flowing through a 1-k ohm what would ther power consumption be?
Power = I^2*R, so P = (5 x 10^-3)^2*(1,000) = 25mW
Why instrumentation validation important?
If a single instrument starts to stray, or vary, its signal could be compounded throughout the rest of the system. If several instruments begin to stray, then the whole system could become unstable. For example, if the thermoprobe on a nuclear reactor's core starts to read low, then the cooling system will 'back off' and allow the core to potentially reach too high a temperature.
What are lissajous pattern when they are produced?
Most often than not we come across bodies undergoing more than one kind of motion simultaneously. Take a wheel of a moving car, for example. It is rotating about the axle and is also undergoing translatory motion. If we were to trace the path of a point on this wheel, it could give us information on the different motions superimposed on that point and the resultant of those motions. The pattern traced out by a point undergoing two or more kinds of motions is termed its Lissajous Pattern.
The difference between Digital signal and analog signal?
I'm not sure if you are speaking of a specific instance.... However, a digital signal is a binary representation of the analog signal. The analog signal is constantly measured and the amplitude (voltage at the time of sample) of the analog signal is converted to a binary number at specific intervals (the frequency of the sample rate). The higher the frequency of the sample rate, the more accurate the representation of the analog signal.
Can I use an HD aerial to receive an FM radio signal?
Sure you can use it. The question is: How effective will it be ? In the real world, the answer is: If it's a choice between an indoor FM antenna and the TV antenna on the roof, then you'll be very satisfied using the roof-mounted TV antenna for FM. Technically, the parts ('sticks') on the TV antenna are not the right lengths for FM, so the TV antenna won't be very efficient for FM reception. BUT ... it'll be a darn sight better than a piece of wire downstairs inside the house. If you live in a rural area, you'll start picking up the distant FM stations that you couldn't quite hear before. If you live in or near a big city with lots of FM stations, you just might start picking up so many that the dial of your radio is crowded, and you have troubled separating out the one you want. If that happens, you may need to get back offof the TV antenna, just because it's working TOO well for your FM radio.
What is dynamic power dissipation?
It refers to transitional of active devices as opposed to steady state devices.
How was transistor shrunk further?
A: The transistor has not changed practically the same size what has changed is the packaging and the technology of mapping substrates
Have they made a projector that projects upward?
There are a number of projectors that can be mounted vertically. It is important to ensure that the cooling system will operate correctly and the manufacturer will be able to advise.
Any projector can be used to project vertically by using a mirror in front of the lens. With the projector horizontal, a mirror at about 45 degrees will direct the image upwards or downwards. The mirror will need to be mounted firmly to avoid slippage and vibration.
Although any mirror can be used, it should ideally be a front silvered or first surface mirror. This type of mirror reflects light on the front surface and avoids a ghost reflection caused by the front and rear surfaces of the glass both reflecting light. An audio visual system integrator may be able to supply mirrors, mounting frames and installation guidance.
What is the difference between 100ohm and 100E?
It is the same, you can use ohm, µ, R or E to represent Ohm, like 2E2 or 2R2 = 2.2 Ohm and 2K2 = 2.2 Kilo Ohm also 2M2 will be 2.2 Mega Ohm.
How do you convert VSE to AVI?
Rename the file and just put .AVI at the end of the file name where the vep file name used to be.
