Electricity...tackle the tricky bits

The size of the current in a series circuit depends on the voltage of the battery (or power supply) and the components in the circuit. Increasing the battery voltage increases the current.

Whether a battery is a constant voltage source or current source

Thus, when you draw current from the battery, the voltage across the resistor goes up which means the voltage across your circuit goes down. Eventually you deplete the battery. When this happens, we can no longer treat all of the parts of the battery in bulk. Parts of the battery will remain charged, other parts will be fully discharged.
