Using ohms law explain how voltage changes in relation to current assuming that resistance remains constant

Ohm's law as a formula is V=IR.So, R=V/I.So, if the R remains constant, then the as the voltage is increased, so will be the current, in proportion.On a graph, that should show as a straight line if, say, V were plotted horizontally, and I vertically. (It's probably easier to change a voltage than it is to change a current, so V would be the independent variable and I would be the dependent variable. The resistance would then be the reciprocal of the slope.

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative.
