if the current is increased what will happen to the resistance?

Question

anonymous · Answer

R=V/I, and hence resistance is indirectly proportional to current. 
Therefore, an increase in current would have the effect of decreased resistance.

Yes, R=V/I but we don't know how V (Voltage) changes with the increase in current. The resistance should be a constant regardless of a change in current.

Current heats a wire and this has the effect of increasing its resistance. The current through a bulb is biggest when it is first switched on. Thus they tend to blow at that point, and more often in winter or colder climes.

Ohms law is an empirical observation. Not maths magic.

It depends, as suggested by the posts above.  The problem doesn't specify why the current increased.  There could of been different scenarios that result in increase of current.  For example, the voltage could of increased and the load resistance had remained fixed, the IR would of equaled the higher voltage with increasing current thru the unchanged resistance.  Or, the current could of increased as a result of increased loading as a result of decreased resistance of the load.
