A. Accuracy A measuring instrument is said to be proper if it has good accuracy measurement results indicate that small uncertainties. It can also be understood as the result of measuring how close to the true value. In this case before a measuring instrument is used, it must be ensured that the condition of the tool truly in good condition ...

A positively charged atom is said if the number of positive charges (protons) in the nucleus more than the negative charge (electrons) in the atomic shell that surrounds it. A negatively charged atom is said if the number of positive charges (protons) in the nucleus less than the amount of negative charge (electrons) in the atomic shell. An atom is ...

As you already know, that not all of the conductive material has a conductivity of the same level, to the movement of electrons. At a particular material, the conductivity can be very low, so that the movement of the electron mobility became an extremely difficult case, even the movement of the electron mobility of certain materials did not last. For ...

As you already know, that dynamically transfer electrons can occur in two ways, namely chemical and magnetic induction. How to chemically produce electricity on batteries / accumulators, and the magnetic induction method to produce electricity in a generator. Electricity generated through a chemical process such as dry batteries (dry cell) has a voltage of 1.5 volts with direct current (direct ...

Electric current is the movement of electric charge in a conductor in one direction due to the influence of external forces. Because naturally in a material or substance, the erratic movement of cargo direction. Electric charge can be either an electron, ion or keduanya.Arus electricity can occur with media solids, liquids, and gases. As you already know, that the electric ...

By doing more in-depth assessment of conceptual knowledge related to the movement of free electrons on an on-menrus, you will be able to meperjelas meaning of electric current. When we talk about the electricity in our shadow is the movement or displacement of free electrons (electron current) continuously. For practical purposes, the flow of electrons movement commonly known as electrical ...
