PROBLEM TO BE SOLVED: To offer a motor driving circuit and a motor driving method which can prevent the breakage of a transistor without enlarging the chip size, concerning a motor driving circuit, which has at least a pair of transistors for supplying motor coils with currents and for ...
In this configuration the switchable magnetic flux source enters into a second switching status—in which the flux through the particles is maximal and in which the particles can be attracted by the switchable magnetic flux source—as soon as the electrical current through the coil is interrupted....
This force is responsible for the flow of charge through the circuit, known as the electric current. Key Terms battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge. voltage: The amount of electrostatic ...

US conglomerate General Electric (GE), which now offers far more than the electricity company it was originally known for, began examining the use of software and analytics as part of its own digitization and productivity initiatives in 2011 – and now offers similar innovations to its ...
Describe how the electric current moves through the simple circuit. How is electrical potential defined? What is the standard unit of energy? Give an example of a physical quantity having neither unit nor magnitude. There are many different ways to express units for Energy. What are th...
Products with more elastic demand, such as budget phones, electric vehicles, solid-state drives, or LCD display monitors, may see consumers either seek cheaper options or delay upgrades if sufficient alternatives (with lower price points due to less tariff impact) are not available. Categor...
