place a magnet on a scale and measure the mass. then make the two magnets same sides in and put one above each other and read mass.
In the colonies of the United States there was no education for slaves. It was against the law to teach them to read and there was no resistance to these policies.

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.

Infinite...a blown fuse is an 'open' in electronics terms. Infinite resistance.It will not read zero on a digital multimeter, it will read as a maximum resistance.A fuse, when good, has zero (practically speaking) resistance. When it blows, it has infinite resistance, thus on a multimeter it will provide a high reading.... When an analogue (not digital) multi-meter is set to ohms it will read zero when blown. If you touch both leads off the meter it will read full scale. if the leads are NOT touching the meter will read zero. so if your fuse is blown it will act like the leads are not touching because it is blown. It is good practice not to touch the exposed lead ends or the fuse under test as the resistance of your body can give a false reading.The ohm scale on an analog multimeter is reversed...when the meter is at the far left, what you might think is zero, it is indicating infinite resistance. When you try and determine the resistance of a fuse that is blown, the meter will not move from the left side of the scale. That is not zero resistance. That is infinite resistance.
Yes. It NEEDS a source to be connected.
Resistance can be determined by measuring the voltage across a component and the current flowing through it, then using Ohm's Law (R = V/I) to calculate the resistance. Alternatively, resistance can be determined by using a multimeter set to the resistance measurement mode to directly read the resistance value.
Your local sports store will be a great place to learn about and check out different brands of resistance bands. You can also read online about resistance bands at: http://exercise.about.com/cs/exerciseworkouts/a/resistance.htm. Enjoy!
To read a soil compaction test probe, insert the probe into the soil to the desired depth, then compare the resistance encountered while inserting and removing the probe. High resistance indicates compacted soil, while low resistance suggests loose soil. Record the depth at which resistance changes occur to assess soil compaction levels.
A VATS (Vehicle Anti-Theft System) key has a resistance chip on the key which is read through the ignition. If the resistance matches the computer then the vehicle will be allowed to start.
If an Alternating Current (a/c) motor is bad. The resistance will read very hi as in an open winding. ie: meg ohms Or very low as in a shorted winding. ie: 0.01 ohms It must not read any resistance to the housing or shaft. The resistance between leads should be a reasonable value and can be determined with : electromotive force divided by inductance equals resistance. example: 215 volt alternating current with name plate full load amperes of 10 should read very near 21.5 ohms resistance between leads.
The resistance of a human body changes, you can divide it in 3 groups: dry body, semi-wet body (sweat,...) and wet body (in a swimming pool,...) the more wet the body becomes, the lower the resistance.
