What is the current drawn by a 10 ohm resistor with 120 volts applied?

To determine the current drawn by a resistor when a specific voltage is applied, Ohm's Law is used. Ohm's Law states that the current (I) in amperes is equal to the voltage (V) in volts divided by the resistance (R) in ohms. The formula can be expressed as:

[

I = \frac{V}{R}

]

In this case, the voltage (V) applied is 120 volts, and the resistance (R) is 10 ohms. Plugging these values into the formula gives:

[

I = \frac{120 \text{ volts}}{10 \text{ ohms}} = 12 \text{ amps}

]

Thus, the current drawn by the 10-ohm resistor under a 120-volt application is indeed 12 amps. This result confirms that the correct answer is the one indicating 12 amps as the current drawn. This understanding is fundamental in electrical circuits, as knowing how to apply Ohm’s Law can help in calculating current, voltage, or resistance in various scenarios effectively.
