Current electricity is the most common form of electricity that is used to power up devices and appliances. Learn the generation of current electricity and more.
and the graph of ac looks like a sine wave, which means the current flows to and fro, our household current changes directions 50 times a second; hence you can see 50hz written on most of our electrical equipment. the below videos help to revise the chapter electricity class 10 frequently...
The main difference between electric current and static electricity is that the electrons or charges flow through the conductor in an electric current. Whereas, in static electricity, the charges are rest and accumulated on the surface of the substance. The electric current is due to the flow ...
Ques. Find the current density passing through a copper wire having a cross-section area of 15 mm² and the current flowing through it is 5 mA.(2 mark) Ques. How is the current density(J) related to conductivity? Explain in detail.(3 mark) Ques. What is the dimensional formula for ...
ElectricityandElectric Charge The most common general formulas used in electrical engineering ●Basic FormulasandCalculations● Relationship of the physical and electrical quantities (parameters) Electric voltageV,amperageI,resistivityR,impedanceZ,wattageandpowerP ...
Shift current photovoltaic devices are potential candidates for future cheap, sustainable, and efficient electricity generation. In the present work, we calculate the solar-generated shift current and efficiencies in 326 different 2D materials obtained from the computational database C2DB. We apply, as...
It has within the electricity field been a long felt need of apparatuses and methods of this type. When such a fault current occurs, it is important that the electric switching device on one hand opens the current path, i.e. breaks the current, as soon as possible for not damaging differ...

Additionally, the boost converter can scale up the solar voltage at low irradiation levels, therefore encouraging the drawing of modest amounts of electricity from solar. The DC link, connected to the input of the 3-φ transformerless inverter, is represented by the end of the boost converter’...
For environmentally sustainable electricity production and use, the number of solar plants and EVs is increasing annually; this impacts the distribution network in terms of power quality. Measurements can provide a closer insight into the solar inverter effect on THDv of the supply voltage [7]. As...
