What does a tarnsistor do?
A transistor is a small electronic device containing a semiconductor and having at least three electrical contacts, used in a circuit as an amplifier.
What is the minimum qualification for the post of electrical lecturers in engineering college?
It depends on the college. With any credible college it would require at least a post graduate degree.
Do televisions have magnets in them?
Yes, at least in the speakers. Some older televisions used them to help direct the electron beam, though mostly electromagnets were used for that.
What should an electrical panel rating be?
Depends on the load. Most residential homes require at the very least a 200 amp service panel.
How much storage does Call of Duty mobile take?
In android, it takes up at least 3GB or more. Depends if you download the weapons/soldier/weapon camos. but its not compatible in my iOS device.
Can you use a 9v adapter on a device that requires 4 AA batteries?
The highest voltage that four AA batteries can be delivering is 6 volts, if they're connected in series, and they may not be. The effect of 9 volts on the device depends on the specific device. But we know that 9 volts is at least 50% overvoltage to the device and possibly more. Chances are high that the device won't like it, and will fail. ('Fail' is engineer talk for 'burn out' or 'burn up'.)
Will a subwoofer drain your car battery?
All electrical devices create at least some amount of drain on your car's battery. Although the amount will vary by device, a properly wired system will charge via the car's alternator with no adverse effects.
How many minimum satellites are required for a Gis device to work?
a GPS device will need at least 3 satellite locks to work.
What are some uses of electromagnets?
In general, electromagnets are used to move things; whether it be ultra small things like molecules or super large things like locomotives or cruise ships. MRI systems use electromagnets to "move" or at least change the polarity of molecules then measures the amount of electromagnetic energy created when the molecules move back. (yes, that's an oversimplification) Tape recorders use electromagnets to move iron oxide molecules on a tape, forcing a specific magnetic orientation of the molecules that can be read when the tape passes a tape read head. Electromagnets are used to move armatures of electric motors, and the armatures are connected to shafts that rotate, propelling a cruise ship or a locomotive. Electromagnets "move" the electron beam of a CRT, allowing the picture to be displayed on older televisions. That is just an example of a few uses of electromagnets. Keep looking, they are all around us.
What Knee replacement device has the least failure rate?
Depends on who you ask. The most reliable results are from the National Joint Registries (from Australia, Britain, and Sweden), which say the DePuy PFC sigma or Zimmer Nexgen (but not Nexgen Flex).
What type of marine sanitation device has the least impact on the environment?
Type I Marine Sanitation Devices tends to have the least impact on the environment.
Exterior electrical service wires should be at least 3 feet away from?
CEC - any window that has the capacity to be opened.The exterior electrical service wires should be at least 3 feet away from any part of any window that is able to be opened.
