Solve the problem. Round your answer, if appropriate.Electrical systems are governed by Ohm's law, which states that V = IR, where V = voltage, I = current, and R = resistance. If the current in an electrical system is decreasing at a rate of 3 A/s while the voltage remains constant at 28 V, at what rate is the resistance increasing (in ?/sec) when the current is 20 A? (Do not round your answer.)
A. 
?/sec
B. 
?/sec
C. 
?/sec
