Fuse → P=IV, P=(I^2)(R), P=(V^2)/(R)

Coulomb's Law → the magnitude of the force between charge q(A) and charge q(B), seperated by a distance r, is proportional to the magnitude of the charges and inversely proportional to the square of the distance between them.

Electric Potential Difference in a Uniform Field → (V) the work done moving a positive test charge between two points in an electric field divided by the magnitude of the test charge

Circuit breaker → when the positive charge of the nucleus equals the negative charge of the surrounding electrons, then the atom is ___

Charging → The separation of electric charges

Power → one joule per coulomb (J/C=V)

Electric field line → E=F/q´

Conventional current → the flow of positive charges

Groundfault interrupter → the process of connecting a body to Earth to eliminate excess charge

Equations with time → the study of electric charges that can be collected and held in one place

Conductor → a material that allows charges to move about easily is called an electric ___

Series circuit → occurs when a circuit with a very low resistance is formed  the low resistance causes the current to be very large, and when appliances are connected in parallel, each additional appliance placed in operation reduces the equivalent resistance in the circuit and increases the current through wires. The additional current might produce enough thermal energy to melt the wiring's insulations, cause a short circuit, or even begin a fire.
