A light bulb has a resistance of 96.8 Ω. What current flows through the bulb when it is connected to a 120 V source of electrical energy?

Sagot :

Answer:

I = 1.23 A

Explanation:

Given that,

The resistance of the lightbulb, R = 96.8 Ω

Voltage, V = 120 V

We need to find the current flows through the lightbulb. Let the current be I. We can use the ohm's law to find it i.e.

[tex]V=IR\\\\I=\dfrac{V}{R}\\\\I=\dfrac{120}{96.8}\\\\I=1.23\ A[/tex]

So, the current flows through the bulb is 1.23 A.
