Measurements can be done with the prisoners in two ways: (1) direct and (2) Indirect. Measurement of prisoners are directly performed by using the ohmmeter. In essence the ohmmeter used to check the value of the electrical resistance. But because of the special characteristics, then the ohmmeter can be used also to examine the different elements dropping in a circuit ...

In everyday life, we can listen to the radio, watch television, use the refrigerator and electric irons. Have you ever watched an electric circuit in radio, television, refrigerator, or iron? Have you ever wondered why radio, television, refrigerator, or the board can function? The use of these tools require electricity. Electric currents occur because of the transfer of electric charges. ...

You already know about the notion of electric current, the flow of positive electrical charge on a conductor of a high potential to low potential. On the battery, there are two poles of different potential. If the two poles are connected by the light through the cable, there will be a transfer of electrons from the negative to the positive ...

When electrons move from a negatively charged end to end positively charged at a conductor, meaning it has made an effort electricity. Electric power is the rate of electron working on an electrical effort. This means that electrical power is the capacity of a business in which electricity is used. Electrical power is measured in watts (W) or kilowatt (kW). ...

Things to consider in measuring the voltage is switch positions and limit measure measuring range (range). If will measure 220 ACV, switch the measuring range must be in a position ACV, and limit measure (range) at number 250 ACV. The same applies to DC voltage measurement (DCV). Equally important to note is the safety factor. Note whether the cable wrapping ...

The hydrogen atom shows the simplest arrangement. Consisting of an electron and a proton (commonly called nuclei). Electrons as carriers of electric charges is called the smallest elementary charge. Electrons are elementary negative charge carriers, protons are elementary positive charge carrier. Figure 1.8 Figure atom schemes: a) a hydrogen atom b) carbon atoms Electron negative elementary charge equal to the ...
