What is cost of voltmeter?
Simple small voltmeters can be bought for less than $10. Most very accurate and reliable ones are between $80 and 300
How do you measure the power input and power output for the step-up transformer?
Power input to a transformer = (voltage across the primary winding) x (current through the primary)Power output = (voltage across the secondary winding) x (current through the secondary)It doesn't matter whether the transformer is used in step-up, step-down or simple isolation.
How do you test a transistor is there any meter to test?
You can do simple resistance tests on the various diode junctions. Measure each of the pairs of diode junctions. Collector-emitter, collector-base, base-emitter. Read the resistance of one junction and then read the same junction with the polarity probes switched. One side should read very high resistance, over 1 megohms. And the other should read a moderate resistance, a few hundred thousand ohms. If this is the case for all three junctions, the transistor should be a good working one.
What is a microwave turnstile junction?
A microwave turnstile junction is a waveguide for use at microwave frequencies that is used as a splitter to derive outputs with different symmetries. There is a pretty good drawing that can be viewed by using the link. Be sure to scroll down. The picture is on page 7 of the article. Consider the four rectangular ports are the "goes outas" and that should help lock it in. Precision in construction would be a must to get an even split, but that makes sense. Those microwaves are tricky. More ports are possible (a bigger turnstile) and a round input waveguide will help solve problems. The geometry (shape) of a microwave turnstile junction sets up a scattering matrix at the junction with a resulting differential symmetry (call it polarity) in the outputs. Keep it simple and it'll be easier to see how it works.
On a Seat Cordoba all bulbs are working yet the headlights wont work why?
More than likely there is a short in your electrical circuit either between the headlights and your switch or in your Headlights fuse. Check under the bonnet near the battery for a fusebox then check for the Headlights or Headlamps fuse then check to see if the fuse has been blown (the fuse will be in a seethrough casing and the circuit will be separated). Another good tool to get for yourself is a simple voltmeter, you should be able to find a voltmeter for about 10 to 30 euros and then read the instructions. When checking for automotive circuits set your voltmeter for DC voltage then place your positive probe on one part of the circuit and your negative probe on another part and note the reading. If the reading fails to read toward normal voltage (12-14VDC) then you have identified the shortcircuit and may be able to replace the shortcircuit or inform your mechanic or dealership or agency of your problem.
A bulb is connected to a battery having a potential difference of 6 V A voltmeter is connected across the bulb What is the reading on the voltmeter when the bulb burns out?
Assuming you're referring to a simple incandescent bulb . . .When the bulb burns out, the filament is open, and it is electrically no longer there.The voltmeter is then across the battery, which is open circuited, i.e. without a load.The meter measures the open-circuit voltage of the battery, nominally 6 V.

What could be the tendencies for the voltmeter if the voltages to be measured exceed the range?
You'd potentially damage the meter. Whether you do or not is immaterial; if the meter cannot measure the range of voltages you are expecting, it will not give accurate readings over that voltage range, thus you should not use it. Buy a different meter that will measure over that voltage range, or use a voltage divider circuit to get a lower voltage at a certain ratio of what is actually in the circuit (this may be difficult to do, or very simple depending on the circuit tested - the key is you do not want to load the circuit with the voltage divider network).
Why are none of the headlights are working on lowbeam but when switched to highbeam all for of them come on for a 1988 brougham?
I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages. I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages.
What is the procedure for measuring current?
A: The procedure is very simple must have a voltmeter and must have a very low value of shunt in series with the circuit whereby the IR drop will be converted into amps. That works for DC only. For AC the signal is rectified and then measured or a flux clamp can measure the current
What is the common example in the electronic device?
A simple pn-junction diode is the common example of a electronic device.
What is a description of Simple P-N junction diode?
The junction formed by the combination of a P- type & N-Type material in known as PN jn diode. It is used as a switch as well as a rectifier.
How do you measure automobile rims?
Simple, grab a tape measure. Take the end and place it on one edge of the wheel and try to make a straight line across to the other egde of the wheel. Read the numbers on the tape and there you go, you've got your measurement.
What is the simple definition of temperature?
a simple definition of tempersture is the measure of how fast particles in an object are moving or the measure of how hot an object is

What can you measure a liquid by?
simple millilitres
How many mound in one tonn?
A maund was an measure of mass used ir a region stretching from the Indian subcontinent to Arabia. Unfortunately, it did not have the same value across this region and so there is no simple answer to the question.
