Atom dan Elektron

Dalam kehidupan sehari-hari,kita dapat mendengarkan radio, menonton televisi, menggunakan kulkas, dan setrika listrik. Pernahkah Anda mengamati rangkaian listrik pada radio, televisi, kulkas, atau setrika ? Pernahkah Anda berpikir mengapa radio, televisi, kulkas, atau setrika dapat berfungsi ? Penggunaan alat-alat tersebut memerlukan listrik. Arus Listrik terjadi karena adanya perpindahan muatan-muatan listrik. Listrik dibedakan menjadi listrik statis (listrik tak mengalir) dan listrik ...

Electrical Energy Consumption Calculation

In some cases the required compute power needs an electrical equipment to ensure the amount of consumption of electric energy used by an electrical equipment. For practical purposes, usually electrical power encoded premises large letters P. Here is an example of calculating the three electrical power to an electrical circuit. Example 1: What is the value of power consumption in ...

Theory Thevenin and Norton

A circuit or linear network, active and resistive containing one or more sources of voltage or current source can be replaced with a voltage source and a series resistance (Theorem Thevenin) or a current source and a parallel resistance (Theorem Norton). The voltage is referred to as a replacement voltage UT and current source called current source IT penggnati resistannya’re ...

Resistor In Electric Circuits

Resistor (resistance = resistance) is a natural manifestation and can be found in all except the super conductive material (super conductor). The nature of a resistor going against the current direction as has been proven in Ohm’s law, where the value of the resistance (resistance) can be assumed and classified as a component of an ideal linear. But the real ...
