1. The problem statement, all variables and given/known data
Suppose a current of 1 A is flowing through a resistor. If this makes the resistor heat up, will the current through the resistor increase, decrease, or remain constant? Assume the voltage applied to the resistor is constant. 2. Relevant equations 3. The attempt at a solution Please help me with this, i'm not sure, but I believe the current will decrease slightly because of the heat dissipated?

Okay, so as the wire heats up the resistance of the wire increases, this causes the current to decrease. Is that correct?

EDIT: provided the resistor is made using wire.
