By reading many of the answers of this particular question I come to realize this is the blind leading the blind. I am afraid someone is going to get killed. Forget about the fact that you cannot measure current by simply taking ammeter probes and measuring across. If you do not already know this then you have no business in this world attempting to directly measure electricity. And the people supplying this erroneous information are well on the road to becoming toast…………

THE EASIEST WAY TO DEMONSTRATE GENERATION OF ELECTRICITY IS TO GET SOME SMALL INSULATED COPPER WIRE AND WRAP IT AROUND A SMALL PILL BOTTLE,  AT LEAST 100 TURNS OR MORE (MORE IS BETTER) CLEAN THE INSULATION OFF THE ENDS OF THE WORE AND ATTATCH TO A VOLTMETER OR A MILLIAMETER.. INSERT A BAR MAGNET INTO THE PILL BOTTLE QUICKLY.  THE METER WILL GO ONE WAY WHEN YOU INSERT THE MAGNET AND WILL GO THE OTHER WAY WHEN YOU PULL THE MAGNET OUT.  THE FASTER YOU MOVE THE MAGNET THE MORE THE METER MOVEMENT.  HOPE THIS HELPS

a hoffman voltmeter can easily be improvised if thats the apparatus you mean? no idiot questions please

spark plugs and wires, check them

v=voltage\no=ohm\nm=milliammeter\n\na tester which test those mentioned aboved. don't use it in measuring resistance(ohms) when the circuit is still connected to a source (voltage)

Yes. You'll need a lemon, a galvanometer or Vmeter, 2 stiff copper wires, a large paper clip, and scissors.\nStrip the insulation off on the ends of the wires. Untwist the paper clip and twist the end of one of wires around it. Squeeze and roll the lemon to loosen the pulp inside. Make two small cuts in the skin of the lemon an inch or so apart. Insert the bare wire and the paper clip through these cuts into the juicy part. The two wires should be close but not touching. Connect the free ends of the two wires to the terminals of the meter.\n\nNow watch the meter move!\n\nExplanation: Electrochemistry causes the two different metals (the copper wire and the iron clip) in the acid (lemon juice) to draw electrons away from one wire towards the other. They flow out of the lemon through one wire, go through the meter and then enter the lemon by the other wire.\n\nYou can even try to make your own galvanometer (an instrument designed to detect electrical currents) if one isn't available to you. You'll need a compass, 15 feet of bell wire (hardware store), and a small rectangular cardboard tray. Place the compass in the cardboard tray. Scrape off 1/2" of insulation from each end of the bell wire. Starting 6" from one end, wind the wire tightly around the box, circling it at least two dozen times. Leave another 6" of wire free on the other end of the tray. Rest your homemade galvanometer on the table horizontally and turn it until the compass needle is parallel to the coil of wire. Use these bell wire ends to attach to your lemon and paper clip.\nIt's fun!

If you mean electroscope then go here to see instructions on building your own:\nhttp://www.exploratorium.edu/snacks/electroscope.html\n\nHere's some more information:\nhttp://en.wikipedia.org/wiki/Electrometer

The meter should have some literature with it.\n\nWrite to the manufacturer and ask for it.

The meter must measure the power you use (and must pay for) using the formula P = IE (power equals current (I) times voltage (E)).  To do so it must accurately dedect the line voltage and electrical current entering your house.  The meter contains an aluminum disk that you can see spinning fast or slow depending upon how many (or few) electrical devices you have turned on.  Inside the meter there are two coils of wire (one on top and one on the bottom of the disk).  One coil senses instaneous voltage that can vary (and even droop in a brownout).  The other coil detects all the current you are using, if any.  With your main circuit breaker open there will be none.  When there is both voltage and current flowing, magnetic eddies are produced that measure and integrate the power being used by spinning the aluminum disk (like a small motor) which is connected to a set of gears that turn the meter numerals.  See the link for an illustration and detailed explanation.  Good luck.

Distill the water. The WATER comes out of the tubes, not the salt.\n    As for testing, just drink a little of it. Do you *LIKE* it?\nNo? Well you better make sure that you don't put it back in the same cup you used for collection.\nOK the water will still pass an electric current through it if it has any impurities. Completely pure water will not.\nUnless you use more than around one volt, in which case the bubbles you see escaping will be hydrogen and oxygen. That means you've gone too far with the testing part.

Same as the way to test a diode. One pin is negative and the other is positive. Set the multimeter to test resistance.\n\nTRansistor is a two diode cirtuit, you have to determine if this is PNP or NPN transistor. Use the negative probe and connect to N or negative pin, use the positive probe of the multimeter and tap the P or positive pin of the transistor. Correct polarity test should show a resistance, if none then its busted.\nWhile reverse polarity should show a ZERO resistance, anything else shows a short circuit.\n\nSCR or silcon control rectifier is like two diode all regulating current outward, test procedure is the same, basic is like testing diode, correct polarity should show a flow in current or a resistance, while reverse polarity test should show a ZERO resistance or no flow.\n\nKnow the part polarity pin first.

You test electronics to make sure they are running properly.
