A light bulb in a battery powered desk lamp has a current of 0042 A and is connected to a 92 V battery What is the resistance in the desk lamp class=

Respuesta :

Answer:

A

Explanation:

Answer: 219 Ohms, C

Explanation:

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

[tex]V = IR[/tex]

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

[tex]9.2 = 0.042R\\\\\frac{9.2}{0.042} = R[/tex]

Solving for R gives us around 219 Ω.
