Please wait for the animation to completely load.

Assume an ideal battery. Vary the resistor and explain which of the graphs are correct and which are incorrect. Pay attention to the labels on the axes (electric potential is given in volts, current is given in amperes, resistance is given in ohms, and power is given in watts). Restart.
