The voltage drop Vab across each of resistors A and B was
Chapter 25, Problem 25.75(choose chapter or problem)
The voltage drop Vab across each of resistors A and B was measured as a function of the current I in the resistor. The results are shown in the table: (a) For each resistor, graph Vab as a function of I and graph the resistance R = Vab>I as a function of I. (b) Does resistor A obey Ohms law? Explain. (c) Does resistor B obey Ohms law? Explain. (d) What is the power dissipated in A if it is connected to a 4.00-V battery that has negligible internal resistance? (e) What is the power dissipated in B if it is connected to the battery?
