Video Física
"Electric circuits are one or more loops of wire which allow current to flow all the way around, usually driven by a battery which maintains a potential difference to keep current flowing. Light bulbs ...
Video Física
"Resistors in series are successive resistors in which the same current cannot simply go through one resistor. We can add resistors, but it increases the resistance of the whole network. If one resis ...
Video Física
"Resistors in parallel consist of two separate independent circuits so that when the current reaches a resistor, the current can choose which to go through. Most homes are wired in parallel so that u ...
Video Física
"Resistor circuits are resistor networks which combine resistors in series and resistors in parallel. Removing a resistor in parallel increases the current flow through the other resistor in paral ...
Video Física
"Resistance is the relationship between potential difference and electric current generated. High resistance needs a large potential difference to generate an appreciable current. Electrons will gener ...
Video Física
"RC circuits contain resistors and capacitors. Immediately after a switch is closed, completing the circuit, the capacitors behave like wires because they have a potential difference of zero. After ...
Video Física
"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. " ...
Hipervinculo Física
"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 ...
Video Física
"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 ...
