Question

A lamp draws a current of 0.50 A when it is connected to a 120 V source? What is the resistance of the lamp?

Answer 1

The resistance of the lamp connected to a 120 V source and drawing a current of 0.50 A is 240 ohms, calculated using Ohm's law.

Step-by-step explanation:

The question is asking for the resistance of a lamp when a current of 0.50 A passes through it, and it is connected to a 120 V source. Using Ohm's law, which states that current (I) equals voltage (V) divided by resistance (R), or I = V/R, we can rearrange the formula to solve for R, which gives us R = V/I.

Substituting the given values into the formula:

V = 120 V

I = 0.50 A

The resistance R would then be:

R = 120 V / 0.50 A = 240 ohms.

Answer 2

For this case we have that by definition, Ohm's Law states that:

`V = I * R`

Where:

V: It's the voltage

I: It's the current

R: It's the resistance

According to the data we have to:

`I = 0.50A\\V = 120V`

Clearing the resistance formula we have:

`R = \frac {V} {I}\\R = \frac {120} {0.50}\\R = 240`

So, the resistance is 240 ohms!

Answer:

240Ω
