gre Posted January 6, 2009 Share Posted January 6, 2009 The SI units for electrical resistance are s^3 * A^2 / m^2 * kg and conductance has the exact opposite units (dimensions). Same with capacitance and elastance. What would you call the opposite of acceleration, s^2 / m .. This doesn't represent deceleration, but does it represent anything? Or Joules (energy) .. s^2 / kg * ms^2 .. I like the idea that nothing can exist without an opposite (inverse) , but I'm not sure if there is an opposite to Joules, etc. Link to comment Share on other sites More sharing options...
Mr Skeptic Posted January 6, 2009 Share Posted January 6, 2009 There is the inverse to these (which is not an opposite), but it could be meaningless. Can you think of something that would have whatever units you selected? Link to comment Share on other sites More sharing options...
