Yes, you can put a carefully selected resistor across the terminals of a battery with no ill effects. Key phrase is "carefully selected." Current may be described in two seemingly opposing ways. You may want to look at is as if the positive charge moves, or if the negative charge moves.
If a positive charges enters the negative terminal of a battery and exits the positive terminal, its potential energy will have increased. If that charge then enters a resistor, its potential energy will decrease as it moves through the resistor, since the charge will “use” its potential energy to heat up the resistor.
If a battery has a negative and positive terminal, there must be a barrier preventing them from neutralizing one another, so how can the potential from either negative terminal ever make it through the top half of the circuit without passing through a battery?
Let's calculate it first then understand why the resistor is at the positive terminal: You are using 2 * AA battery. Each AA battery has 1.5 volts. It means the total voltage is 3 volts because you are using two batteries. V = 3 volts I assume that you use 100 ohm resistor. The current that should flow in the circuit = 3 / 100 = 0.03 ampere
In a battery circuit diagram, the positive and negative terminals are connected to different components. The positive terminal is typically connected to the load, which is the device or circuit that the battery powers. This allows the current to flow from the battery, through the load, and back to the negative terminal.
The real electrons moves from the negative terminal to positive terminal. But that does not mean we should put the resistor at the negative terminal. Current pass or flow inside the wire and If you want to put something to interrupt it or make it slow down, you can put it in any place in series with the wire and it will interrupt the current.

This is because the negative terminal of the battery has an excess of electrons, while the positive terminal has a deficiency. When a resistor is connected, it creates a path for the electrons to move through, resulting in an electric current. Here''s a step-by-step breakdown of the process: Battery Setup: A battery has two terminals; negative ...

why would you ever put the resistor on the positive side

Why are leads from the negative terminal considered grounds?
It is the positive voltage potential that is being regulated. The negative terminal is acting as the reference point (common node) in the circuit. In the example of powering an LED from the 9V battery, it doesn''t matter if the resistor was placed between the positive terminal and the LED, or the LED and the negative terminal.
