Hello! I don’t understand the entire part ( the science bites)...anyone able to explain? Thanks a lot!!

Answer:
resistance is directly proportional to the temperature
Explanation:
when current flow through the circuit then heat is produced in the circuit
and due to heat production the temperature of the circuit will be increase by the which resistance of circuit will be increases
example
when light glow then heat produce in the filament and then resistance of the filament will be increases
plz...
mark it as a brilliant answer
