Final answer:
Technician A is correct about Ohm's Law and total current in a circuit, while Technician B is incorrect. The answer is option A.
Explanation:
Technician A is correct in saying that Ohm's Law can be used to calculate the total current flow in a circuit. Ohm's Law states that current (I) is equal to voltage (V) divided by resistance (R), expressed as I = V/R.
Technician B is incorrect in stating that Ohm's Law can be used to calculate the total resistance in a circuit. Instead, Ohm's Law is used to determine individual resistances or the current flowing through a circuit.
Therefore, option A is the correct answer.
