In what unit are electrical currents measured
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. WebI = E / R. I = 260 V / 240 Ω = 1.083 A. Example 3: Find the applied voltage, when given circuit resistance of 100 Ω and circuit current of 0.5 amps. Solution: Since circuit resistance and circuit current are known, use Ohm’s Law to solve for applied voltage. E=IR. E …
