Document Summary
Electric charge [q: charge of one electron as: 1. 6x10-19, so one coulomb of charge is equal to. 1/1. 6x10-19 or 6. 25x1018 electrons: q = 1 coulomb = charge of 6. 25 x 1018 electrons. Electric current is the ow of electric charge in the form of free electrons. The value of a current is on ampere. If point a is positive with respect to pt. B, moving a positive charge around a closed circuit from a to b (or a negative charge from b to a) requires work. The di erence between the two points is the voltage polarity: the sign (+) and (-) represents the current ow. "1: conventional current ow gives the ow of electrical current from positive to negative and electron current ow around a circuit from the negative. Saturday, september 1, 2018 terminal to the positive: ac waveforms, alternating current, (ac) is current that changes direction cyclically, passing.
