An electric force is an attractive or repulsive force between two charged objects. Electric forces are attractive when two objects have opposite charges and repulsive when two objects have like charges. Electric forces are different from magnetic forces, although the two are strongly related.Know More
Static electric forces are relatively easy to observe in action. For instance, conventional foam or packing peanuts tend to stick to hands and other objects. This is due to a charge in the surface of the peanut, which is attracted to the opposite charges in hands or other objects. Similarly, removing a wool hat can cause hair to stand on end. As the hat rubs the hair, it picks up an electrical charge; this also leaves each hair with a charge. Because the hairs have like charges, they try to move away from one another, and stand on end.
Electric forces and magnetic forces are both products of electric charges, but while electric forces can be from static or moving charges, magnetic forces only arise when a charged object is in motion. Permanent magnets are possible in certain metals because of the motions of electrons around the atoms that compose them. Electric charges are caused by the presence or absence of electrons and so moving electrons around an atom actually produce a small magnetic field.Learn more about Electricity
Electrical energy in the form of electricity is primarily manufactured by using massive generators equipped with turbines. It can also be generated by transforming one form of energy, which is stored in certain materials, into electrical energy.Full Answer >
A static force refers to a constant force applied to a stationary object. A static force is too weak to move an object because it is being countered by equally strong opposite forces.Full Answer >
Electromotive force is the difference in electrical potential between two points that compels electricity to flow to an area of lower potential in order to equalize charge. According to the HyperPhysics website, the force is measured in volts and frequently abbreviated as "emf."Full Answer >
Main electrical panel wiring refers to the wiring diagram of a main electrical panel, which houses the electrical power from the electric meter and circuit breakers. The main wiring usually consists of two thick black wires that comes from the utility company via the electric meter: the main circuit breaker and an earth-grounding wire. The grounding wire connects to a solid copper rod driven into the soil below the panel.Full Answer >
