How a battery works
The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device for.

Why does voltage reading increase the greater the resistance load?
So the lower R4 and R5, the more current, and therefore the more voltage loss in R1, which means less apparent voltage on the battery. Another way to see it is that you have 2 resistors in series (R1 and {R4, R5}). You split the voltage of the battery (10V) into the 2 resistors : the bigger resistor in proportion gets the biggest share.
