Ответ:
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.
