What is there a difference in house current( 110V ) and many electronic devices rated for 120V( usually computer hardware ), and large voltage ranges( between 100V and 240V ) on electronic devices?

David -

110V is not current, it is EMF - electromotive force - how hard the electrons are being pushed. Current is measured in amperes.

More specifically, 110V is not significantly different from 120V... some ask for 115. The power company adjusts the voltage and it may vary slightly from place to place (at least within the US). Where I live the power company sets the voltage at 117 volts.

240 volts is very different, but you may consider anything from 110 to 120 as interchangeable.
