Electrical devices such as light bulbs and heaters that convert electricity directly into other forms of energy, such as heat, can operate effectively using both alternating and direct currents. However, nearly all modern electronic devices such as laptops, mobile etc., require direct current for ...
Types of Electric Motors History of Motors 💡 Key learnings: Electric Motor Definition: An electric motor is a device that converts electrical energy into mechanical energy using magnetic fields and electric currents. Core Functioning: The main principle behind all electric motors is Faraday’s Law...
Components of Electric Circuit How Do Electric Circuits Work? Lesson Summary Register to view this lesson Are you a student or a teacher? What are the main types of circuits? What are the components of a circuit? All Electricity Topics ...
This type of vehicle also has an electric motor, but instead of having a battery storing the energy, they have a fuel cell that produces electricity at the desired time. This unit, which is usually a hydrogen cell, generates electricity from a chemical reaction process called electrolysis: the...
Electricity: Short Circuits & Direct Currents The mechanical output power must be provided by an electrical input power. The original stator currents shown in thefigureare just sufficient to produce the rotating magnetic field. To maintain this rotating field in the presence of the rotor currents of...
A PCB (Printed Circuit Board) or PWB (Printed Wiring Board) is a complex circuitry of copper tracks on a heat resistant material called PCB substrate. Electronic components are soldered on this Circuit Board to control flow of electricity in a preset matter for the electronic device to work...
Type of diode that allows for reverse direction of current at a certain voltage How currents flow in a diode Arrow in the diode schematic symbol Skills Practiced Reading comprehension - ensure that you draw the most important information from the lesson on types of diodes Information recall...
These types of diodes can also be used to generate electricity. For some applications, PIN diodes work very well as photodetectors. Read more about . . . . Photo diode. PIN diode: This diode type has areas of P-type and N-type silicon, but between them there is an area of intrinsic...
Types of terminal blocks include: Schroefklemmen Spring-cage connections Push-in terminals You can easily add or remove wires as needed. Many terminal blocks include built-in testing points and marking strips for better organization. Industrial terminal blocks can handle high currents and voltages saf...
Most of the electricity is generated by fossil fuels such as natural gas, coal, and nuclear energy. However, many countries around the world are using alternative sources such as hydropower, biomass, geothermal, and solar power. In science, the First Law of Thermodynamics states that energy can...
