If the current is not the same at different points in a closed electrical circuit, by definition charge will build up. The example of this is adding a capacitor in series with the resistor and battery. The capacitor passes no current. When you connect the battery, the current flows to the capacitor plates and voltage builds up on the plates.

$begingroup$ 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

You will need to measure current and voltage in multiple places on several different circuits.

When the battery is open you are measuring an open cell voltage. When the battery is in the system it''s closed cell voltage under load. You are dropping some voltage across the internal impedance of the battery because your system is drawing current when the measurement is being made (so at the terminals the voltage is indeed lower).

Learn MoreHere is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
When current flows from a battery, does voltage decrease? I understand voltage to be a potential for electrons to be pushed through a circuit. However, in a battery, you have an electron build-up that creates the voltage. Once current begins to flow, electrons are now moving through the circuit.
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
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
Too much voltage can cause a fire or a short circuit.
