Question

There is a current of 0.73 Amps through a light bulb in a 120 Volt circuit. What is the resistance of this light bulb?

Answer 1

ANSWER

$164.38\text{ }\Omega$

EXPLANATION

To find the resistance of the light bulb, we have to apply the formula derived from Ohm's law:

$V=IR$

where V = voltage

I = current

R = resistance

Therefore, solving for R in the formula above, we have that:

$\begin{gathered} R=\frac{V}{I} \\ \\ R=\frac{120}{0.73} \\ \\ R=164.38\text{ }\Omega \end{gathered}$

That is the answer.
