"Potential difference is what we use to generate current and to make it do what we want it to. Batteries serve as a constant source of potential difference in order to force the current to flow. " ...

"The law of conservation of charge states that electric charge can neither be created nor destroyed. In a closed system, the amount of charge remains the same. When something changes its charge it doe ...

"Conductors have a flow of charge through the conduction band. Metals are extremely good conductors. In general, charge congregates at sharp points. Conductivity is related to electric fields by th ...

"Charge transfer can happen through friction, induction or conduction. An electroscope is a device which detects charge." Fuente: BrightStormCharge Transfer es un video-tutorial (en inglés) de ©Bright ...

"Like currents in series, charge is the same when capacitors are connected in series but the potential difference adds. Unlike currents in series, effective capacitance is found by (1/effective ca ...
Video Física
"Capacitors in parallel allow the charge a choice of capacitors. Potential difference is the same with multiple parallel capacitors but the charge adds. Like resistance in series, adding capacitors ...

"Capacitors store charge and energy. Parallel plate capacitors generally composed of two oppositely charged plates separated by a distance. The equation that we use to determine capacitance is capaci ...

"Capacitor circuits are circuits which flow until the capacitors are full. Once the capacitors are full, it is called steady state. " Fuente: BrightStormCapacitor Circuits es un video-tutorial (en ...
"Ohm's law defines a concrete relationship between potential difference and current flow. This relationship is satisfied by all ohmic materials according to the equation potential difference = - curre ...
"Atomic emission spectra are unique spectra of light emitted by an element when electricity is run through it or when it is viewed through a prism. Because they are unique, they can act as an element’ ...
