In this simple circuit, we have a 12 V battery and a bulb with a resistance of 24 ohms. When the switch is turned on, the ammeter connected in the circuit will read a certain value.

To determine the current flowing through the circuit (which is what the ammeter measures), we can use Ohm`s Law: V = I * R, where V is the voltage, I is the current, and R is the resistance.

In this case, the voltage of the battery is 12 V, and the resistance of the bulb is 24 ohms. Plugging these values into Ohm`s Law, we can calculate the current:

12 V = I * 24 ohms

Solving for I, we get:

I = 12 V / 24 ohms

Simplifying, we find that the current flowing through the circuit is 0.5 A.

Therefore, the correct answer is option 1: 0-5 A. The ammeter will read a value between 0 and 5 A.
