Answer:

4 amperes

Explanation:

Using the formula; V = IR

Where;

V = voltage (volts)

I = current (amperes)

R = resistance (ohms)

From the formula; I = V/R

According to the information provided in this question, the resistance of circuit (R) is 3 ohms while the voltage (V) produced by the cell in the circuit is 12 volts.

Therefore, I = 12/3

I = 4 A or amperes.
