What is the resistance of a lamp that operates at 120 volts and requires 0.83 amps of current?

Explanation:
To determine the resistance of the lamp, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). This can be expressed mathematically as: \[ R = \frac{V}{I} \] In this scenario, the voltage is 120 volts and the current is 0.83 amps. Plugging these values into the formula gives: \[ R = \frac{120 \text{ volts}}{0.83 \text{ amps}} \] Calculating this: \[ R \approx 144.58 \text{ ohms} \] Thus, the resistance of the lamp is approximately 144.58 ohms, which corresponds to the correct answer. This calculation illustrates how Ohm's Law is applied to find resistance when voltage and current are known.

To determine the resistance of the lamp, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). This can be expressed mathematically as:

[ R = \frac{V}{I} ]

In this scenario, the voltage is 120 volts and the current is 0.83 amps. Plugging these values into the formula gives:

[ R = \frac{120 \text{ volts}}{0.83 \text{ amps}} ]

Calculating this:

[ R \approx 144.58 \text{ ohms} ]

Thus, the resistance of the lamp is approximately 144.58 ohms, which corresponds to the correct answer. This calculation illustrates how Ohm's Law is applied to find resistance when voltage and current are known.
