WebMar 26, 2016 · An electric current that flows continuously in a single direction is called a direct current, or DC. The electrons in a wire carrying direct current move slowly, but eventually they travel from one end of the wire to the other because they keep plodding along in the same direction. The voltage in a direct-current circuit must be constant, or at ...

WebElectrical. Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called "electrical charge") flowing past a point in a circuit over a given time. WebResistance does oppose the current flow. Although in a series circuit the current is the same at all points in the circuit, the resistor resists the amount of current that can flow. For example lets say you had a circuit with a battery of voltage 10 V and there was a 2Ω resistor. Using Ohm's law, you can find that the current will be 5 A.
