General electrical theory & principles
WebFeb 24, 2016 · Working Principle of Electric Generator. When a conductor moves in a magnetic field, an emf is induced across the conductor. This is the only basis on which each and every rotating electric generator works (such as portable generators ). According to Faraday’s law of electromagnetic induction, when a conductor links with a changing flux, … Webopposite electrical sign attract (unlike charges attract). 2.1.1 Insulators and Conductors Materials that do not readily allow charges to move are known as insulators, or nonconductors. Glass and rubber are common examples of insulators. If electric charges move under the influence of electric forces, the material is known as a conductor ...

There are two types of current, direct current (DC) and alternating current (AC). DC is current that flows in one direction with a … See more The most fundamental law in electricity is Ohm’s law or V=IR. The V is for voltage, which means the potential difference between two charges. In other words, it is a measurement of the work required to move a unit charge … See more Now, let’s apply Ohm’s law to the following circuit (for exercise purposes only, circuits are theoretical) and calculate the voltage and current supplied to each load.
