Real-world batteries do not have zero internal resistance. When one connects a load (resistance) to a battery, current begins to flow and the open-circuit potential is divided between the battery's internal resistance and the resistance of the load. Thus, one will measure a lower voltage at the battery terminals when a load is connected, compared to no-load conditions.
To determine the Thevenin equivalent resistance (Rth) of a circuit, first, you need to remove the load resistor from the circuit. Next, you can deactivate all independent sources: replace voltage sources with short circuits and current sources with open circuits. Finally, calculate the equivalent resistance seen from the terminals where the load was connected, which may involve combining resistances in series and parallel as necessary. This value represents the Thevenin resistance of the circuit.
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
When an extra globe is added to a circuit, the total resistance depends on how the globes are connected. If they are connected in series, the total resistance increases because the resistances add together. If they are connected in parallel, the total resistance decreases, as the overall resistance is reduced by the additional path for current flow. Therefore, the change in total resistance depends on the configuration of the globes in the circuit.
To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
The net resistance of the circuit connected to the battery in Figure 1 is the total resistance that the current encounters when flowing through the circuit. It is calculated by adding up the individual resistances of all the components in the circuit.
In principle, it is infinite. I have not connected a parallel circuit in ages.

The resistance of the load is what causes an electric current to flow in a circuit.

The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).

In a complex circuit with various elements (resistors, capacitors etc.) and one battery, the various circut elements contribute to draw a certain amount of current "I"from the battery at some terminal voltage "V". The "equivalent" resistance of the various circuit elements is that resistance "R" which will draw the same current , at the same terminal voltage, as the complex circuit. So to find "R" you simply imagine replacing the complex circuit with "R" by attaching "R" across the terminals of the battery and use Ohms law to find "R" , demanding "I" and "V" are the same. So then R = V/I.
This circuit is a series circuit, as the current flows sequentially through resistor 1, then through resistor 2, before returning to the battery. The same current passes through both resistors, and the total resistance is the sum of their individual resistances. The voltage across the circuit is divided between the two resistors according to their resistance values. Additionally, if one resistor fails, the entire circuit will be interrupted, stopping the current flow.
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

The current depends on what is connected to the battery's terminals. If nothing is connected to it, then there is no current, and the battery lasts quite a while. In general, the current is 1.5/resistance of the external circuit connected to the battery until that number gets too big, and then the voltage of the battery sags, because it can't deliver that much current.
