$begingroup$ If you are asking about motors rather than the term "draw", the resistance does not change under load but something called the back-EMF does. The back EMF of a freely spinning motor will cause the current to be at its minimum. The back-EMF disappears when the motor is stalled and you are left with the resistance of the windings which is relatively

Guide 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.

6 Frequently Asked Questions about “How does the battery change the power supply voltage”
How does voltage affect battery capacity?
Generally, a battery's capacity is directly proportional to its voltage. As the voltage increases, the capacity also increases, allowing the battery to store more energy. This is why lithium-ion batteries with higher voltage typically offer longer usage times. 2. The Relationship Between Voltage and Discharge Curve
Does battery voltage change during lifecycle?
Yes, the battery voltage changes throughout its lifecycle, most notably during charging and discharging. During Discharge: As a battery discharges, its voltage gradually decreases.
What happens if a battery reaches a higher voltage?
If you're trying to output more current than your battery can source, than the voltage across the load goes down. V=IR; in the beginning of the discharge (cycle) there is more current coming out of the battery, which shows up as a higher voltage, and in the end, there is less, which translates into a lower voltage.
What happens when a battery is discharged?
During Discharge: As a battery discharges, its voltage gradually decreases. For example, a lithium-ion battery will drop from around 4.2V (fully charged) down to 3.7V, then further to 3.0V (cut-off voltage), after which the device will stop working. During Charging: When charging, the battery voltage increases.
Why do older batteries deliver lower voltages than new ones?
Internal Resistance: As a battery ages, its internal resistance increases, which can affect the voltage under load. This is one reason why older batteries tend to deliver lower voltages than newer ones. Part 3. Various types of voltage
Is a battery a constant voltage source?
A battery is a time-varying constant voltage source. In order to understand this a little bit better, you have to understand why an AC-DC power supply is not constant voltage. The source of the electrons across an AC-DC converter comes from free electrons on a conductor.
