What is light's elementary particle? How is an electric field created? What is dark energy made up of? How did the light bulb created by Lewis Latimer work? Where does the sun's energy come from? Can dark matter be created? What makes up the sun?
Static electricity or ESDis an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of in...
Point charges produce electric field which is defined as the electric force per unit charge. If the point charge is positive, the electric filed is pointing outward. If the point charge is negative, the electric field is pointing inward. The magnitude of the electric field is det...
How is Electricity Generated? Electricity is generatedor produced by turning or rotation of turbines. These turbines can be rotated by any means – coal, steam, nuclear energy, renewable energy such assolar energyetc. In most power plants, turbines are rotated by the pressure of steam. This ...
How is energy efficiency calculated? To learn more about the energy efficiency of devices, it is important to know the calculation used to assess performance in terms of the ratio of energy used to energy produced. To determine the exact figure that corresponds to the efficiency of a system, ...
That is, in an external magnetic field, it moves just as its equivalent magnet would move; further, it and its equivalent magnet cause the same force and torque on a distant magnet. This equivalence has extraordinary implications: it enables one to derive all the important results describing ...
To explain how electric current is produced due to an imbalance of charges, we can follow these steps:Step 1: Understanding Charge Imbalance - Concept: Electric current is produced when there is an imbalance of
Electric Current All matter, including the iron rod of an electromagnet, is composed of atoms. Before the solenoid is electrified, the atoms in the metal core are arranged randomly, not pointing in any particular direction. When there is a current, the magnetic field penetrates the rod and rea...
Electric energy is produced in the generators. By using the principle of electromagnetic induction, the magnetic field around conducting wires is changed and this creates the potential difference. This results in the formation of electric energy. Show More ...
How do you charge an electric car? What do you need to know about plug types? And where can you find a charging station? Read on for answers to these questions, and other important information about electric cars!
