Question

If the voltage and current increase, what happens to the resistance?

Answer 1

What is the material ?

Answer 2

according to Ohms law .... i spose it depends on what the ratio of the increases are.

Answer 3

"Assuming" that the voltage and current increased as a result of increasing the value of the battery such as replacing a 6 volt with a 12 volt, would cause an increase in both voltage and the current with the resistance remaining constant. But if for example we increase the load on lets say on an engine generator, this would result in an increase in current and the sourcer voltage would tend to go down, but the regulator would then increase the throttle to the engine bringing the voltage back up. For example lets say the radio mounted on jeep, the transmitter is keyed causing a need for extra current (increased load reduced resistance) the jeeps engine will feel the increasing load (the jeeps electrical system is powering the radio) you would cause the engine to labor increasing the power to the radio.

The question needs to be expanded, providing the condition or cause of the increase of voltage and current. One thig for certain as the voltage and current increases, the resistive load will soon be receiving excessive power and and burn up.
