Question

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?

Answer 1

I = 1.23 A

Step-by-step 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.

`V=IR\\\\I=(V)/(R)\\\\I=(120)/(96.8)\\\\I=1.23\ A`

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