batteries
Technically, voltage cannot be drawn because its a potential energy between 2 points like gravitational pull. Thus, when the multimeter probes is placed on the resistor, it would draw the full voltage of the battery, the thing that is drawn would be current which causes the galvanometer on the multimeter to deflect.

How Much Power Do 3 AAA Batteries Produce?
The maximum current that a AAA battery can supply depends on the specific type of battery and the load that it is powering. Alkaline AAA batteries typically have a maximum current rating of around 1 amp, while nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) AAA batteries typically have a maximum current rating of around 2 amps.

So the voltage at no load, that you are saying in your case is of 9V, is the exact voltage across the battery that is not able to let a current flow in either direction. So those 9V are the result of a thermochemical equilibrium where the tendency to let current and reaction flow in a direction is equal to the tendency to let current and reaction proceed in the opposite direction.

How many volts does a battery have?
Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps. Advantages and Disadvantages of Series Connections
What if two batteries are connected in series?
Let's consider a simple example with two batteries connected in series. Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps.
How do you connect a battery in a series?
The series connection of batteries is shown in Fig. 1 (a). N number of identical batteries with terminal voltage of V volts and current capacity of I ampere each are connected in series. The load is connected directly across the series combination of N batteries as shown in Fig. 1 (a). The load voltage is given by, VL = (V + V + + V) ..
Do all batteries supply the same amount of current?
If all the batteries are of same current rating then they supply equal amount of current. But, if they are of different current ratings, then they share current in proportion with their current ratings. The batteries are available with some specific terminal voltages. e.g. 6 V, 12 V, 24 V, 48 V etc.
What is the difference between a battery and a series battery?
Battery Cells Definition: A battery is defined as a device where chemical reactions produce electrical potential, and multiple cells connected together form a battery. Series Connection: In a battery in series, cells are connected end-to-end, increasing the total voltage.
Why should a battery be connected in series or parallel?
If we want to have some terminal voltage other than these standard ones, then series or parallel combination of the batteries should be done. One more reason for connecting the batteries in series or parallel is to increase the terminal voltage and current sourcing capacity respectively. Connection diagram : Figure 1.
