1.) using ohm’s law, explain how voltage changes in relation to current, assuming that resistance remains constant.
2.) as the electric current in a lightbulb is slowly increased the filament glows more and more brightly. why does this happen?
3.) why did some of the lightbulb’s you tried burn out?
4.) why is there zero current when a lightbulb burns out?
