What current would pass through a circuit with a total resistance of 10 Ohms and a voltage of 60V?

5A 6A 3A 7.5A

Correct Answer:

Explanation:

To determine the current passing through a circuit given the total resistance and voltage, Ohm's Law is applied. Ohm's Law states that the current (I) in a circuit is equal to the voltage (V) across the circuit divided by the total resistance (R) of the circuit. The formula can be expressed as: I = V / R In this scenario, the voltage is 60 volts and the total resistance is 10 ohms. Plugging these values into the formula yields: I = 60V / 10Ω = 6A This calculation demonstrates that the current flowing through the circuit is 6 amperes. Understanding how to effectively apply Ohm's Law is crucial for analyzing circuits in corrosion prevention and control, making this knowledge particularly relevant for professionals in the field.
