2.ELECTRICAL QUANTITIES

2.1.VOLTAGE OR POTENTIAL DIFFERENCE:
The amount of energy that of generator (electrochemical cell or battery) can transfer to electrons depends on its voltaje (V) or electric tension.This is measured in volts (V).
















2.2.MEASURING ELECTRIC CURRENT:
Electric current (I) is the charge or number of electrons that flow throungh the cross-section of a conductor every second. We can express this methemetically as follows: I = Q/t

Electric current is measured in amperes or amps (A) in the international system or SI.
