What is the relationship between the electrical and magnetic forces in light? What does it mean for electric current to be a scaler? What type of friction produces electromagnetic forces? What is the difference between Electro-Motive-Force and Potential-Difference?
To convert electrical energy to light, heat, or movement, an electrical circuit must have resistance. Resistance is an inherent obstacle to electron flow in conductors. Types of resistance: Four main types of resistance forces are, Friction: Friction is the force that prevents solid surfaces, flui...
The force exerted by a magnet on other magnets is called magnetic force. Magnetic force and electrostatic force act on an object from a distance. That’s the reason they are non-contact forces. The strength of gravity is an attractive force that is exerted by the Earth on objects, which ...
Because electricity is ordinarily invisible to the naked eye, someone who intends to work as an electrical engineer should be curious about mysterious forces that significantly affect the universe but aren't obvious to a layperson. A future electrical engineer should have a powerfu...
The unit of electric charge is the coulomb, which is defined as the amount of electricity that is conveyed by anelectrical currentof 1 ampere in 1 second. Atoms, which are the basic units ofmatter, are made of three types of particles:electrons,neutrons, andprotons. Electrons and protons th...
Two 700 kg masses (1543 lb) are separated by a distance of 0.45 m. Using Newton's law of gravitation, find the magnitude of the gravitational force exerted by one mass on the other. Gravity and magnetism are examples of: a. friction b. electrical forces c....
Static electrical forces build up between the fabric of the socks and carpet in effect charging the person. By spreadsheet — On Sep 28, 2010 Electrostatic charges are some of the hardest to grasp when learning about them in school. When we think of magnets, those cute and sometimes obno...
Theelectrostatic forcedescribes the force between electrical charges that are slow moving or at rest. The electrostatic force leads to attraction between oppositely charged objects and repulsion between objects with the same charge. Microelectromechanical systems (MEMS) exploit electrostatic forces to actuat...
While permanent magnets are magnetic no matter what the situation is, an electromagnet requires current sent through them to show electrical and magnetic properties such as field and force. Permanent magnets have chemical and physical compositions of atoms, alloys and other materials that allow charge...
What are the units of power? What is strength resistance training? What is gravity? What are examples of field forces? What is better to have: torque or horsepower? What is cooperative binding? What is impulse in biomechanics? What is an action reaction pair?
