In A Circuit Voltage And Current Are
A flow of electrons forced into motion by voltage is current.
In a circuit voltage and current are. The voltage between two points is equal to the electrical potential difference between those points. Voltage is sometimes described as the push or force of the electricity it isn t really a force but this may help you to imagine what is happening. This brings us back to georg ohm. Voltage is the cause current is the effect.
Current sources are the opposite to voltage sources in that they like short or closed circuit conditions but hate open circuit conditions as no current will flow. It is actually the electromotive force emf responsible for the movement of electrons electric current through a circuit. Voltage is the cause and current is the effect. Introduction to electric circuits and electricity.
Because it takes energy to force charge to flow against the opposition of resistance there will be voltage manifested or dropped between any points in a circuit with resistance between them. Voltage and current in a practical circuit chapter 1 basic concepts of electricity pdf version. Includes kirchhoff s voltage law and kirchhoff s current law. Voltage attempts to make a current flow and current will flow if the circuit is complete.
