A silicon rod (at 30 degrees celsius) with a uniform cross section connects to a battery with 9 Volts of terminal voltage and .50 A current flows. Temperature of the rod is increased to 30 degrees celsius.

A) what is new resistance of rod?

B) How much current does the rod carry at 35 degrees celsius?

C) If one wanted to cut the current from its room temperature value of .50A to .40A, what temperature would the rod need to be?
