I'm a new student studying electronics and I'm not quite understanding some information about conductance. If resistance is added in Parallel, would the conductance increase or decrease? Also, if resistance was added in Series, would that conductance increase or decrease? And the inverse formulas aren't really making sense either. Is finding the conductance across a load as simple as 1/R=G? Like, is the conductance of a 500 Ohm resisitor 0.002, and what would the conductance total be if a second 500 Ohm resistor was added 1) in Series and 2) in Parallel? I appreciate any help I could get with this information.
