A battery has a short circuit current of 30 A and open circuit voltage...
To find the current flowing through the electric bulb, we can use Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R).

In this case, the voltage of the battery is 24 V and the resistance of the electric bulb is 2 Ω.

Using Ohm's Law, we can calculate the current as follows:

I = V / R

I = 24 V / 2 Ω

I = 12 A

Therefore, the current flowing through the electric bulb is 12 A.
