Basic Electrical Laws

Ohm’s law (which should be familiar) is a very useful rule. Note that it only applies to resistive loads however. The impedance of other passive components may vary with (e.g.) frequency (e.g. capacitors) and many components do not obey this rule at all (diodes, transistors etc.). Resistance determines how much charge flows per second when …
