Question

HELP PLEASE ASAP URGENT: A light bulb whose resistance is 240 ohms is connected to a 120 voltage source. What is the current through the bulb? Identify all of your data, write the equation, and show all work.

Answer 1

Do you know the formula to find current?

Answer 2

this? P = I × V. P = power

Answer 3

Nope V=IR
I=V/R.
Now put the given values.

Answer 4

I=current
V=voltage
R=resistance

Answer 5

ok thank you ill put those in really quick

Answer 6

so it would be I=120/240

Answer 7

Yep.

Answer 8

and then what do i do from there to complete what the question is asking?

Answer 9

so the current would be 0.5 correct?

Answer 10

Yes and don't forget to write its unit.

Answer 11

ok and then is that all i had to do for this question??

Answer 12

Yeah thats it.

Answer 13

thanks so much!
