Question

A light bulb in a battery powered desk lamp has a current of 0.042 A and is connected to a 9.2 V battery. What is the resistance in the desk lamp?

Answer 1

A

Step-by-step explanation:

Answer 2

Answer: 219 Ohms, C

Step-by-step explanation:

To find the resistance, you can use Ohm's Law:

`V = IR`

Where V is the voltage, I is the current, and R is the resistance.

`9.2 = 0.042R\\\\(9.2)/(0.042) = R`

Solving for R gives us around 219 Ω.
