a stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.

The sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.

electric charge can neither be created nor destroyed.

a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this."graphite is a reasonably good conductor of electricity"

a substance or device that does not readily conduct electricity.

touching a negatively charged object to a neutral object. Upon contact, electrons moved from the negatively charged object onto the neutral object. When finished, both objects were negatively charged.

a charged object is brought near but not touched to a neutral conducting object. The presence of a charged object near a neutral conductor will force (or induce) electrons within the conductor to move.

a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

a flow of electric charge.

a region around a charged particle or object within which a force would be exerted on other charged particles or objects.

two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

a path in which electrons from a voltage or current source flow. 

by multiplying the voltage in “volts” by the current in “amps” we arrive at an answer in “watts.”

an electromotive force or potential difference expressed in volts.

that the current through a conductor between two points is directly proportional to the voltage across the two points.

a circuit in which resistors are arranged in a chain, so the current has only one path to take.

is one that has two or more paths for the electricity to flow, the loads are parallel to each other. 

the rate, per unit time, at which electrical energy is transferred by an electric circuit.

an instrument for measuring electric current in amperes.

an instrument for detecting and measuring small electric currents.

an instrument used for measuring electrical potential difference between two points in an electric circuit.

an electrical machine that converts electrical energy into mechanical energy.

the production of voltage or electromotive force due to a change in the magnetic field. Electromagnetic induction was discovered by Michael Faraday in the 1830s. an electrical circuit of lower resistance than that of a normal circuit, typically resulting from the unintended contact of components and consequent accidental diversion of the current.an automatically operated electrical switch designed to protect an electrical circuit from damage.provide (a circuit or electrical appliance) with a fuse. V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin. The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.well balanced and sensible.the ability to do work. Energy comes in different forms: Heat (thermal) Light (radiant) Motion (kinetic)a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field. a region around a magnetic material or a moving electric charge within which the force of magnetism acts.each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically. the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field. each of two regions of intense radiation partly surrounding the earth at heights of several thousand kilometers.
