Question

a light bulb has a resistance of 360 . what is the current in the bulb when it has a potential difference of 120 v across it? 0.33 a 3 a 480 a 43,200 a

Answer 1

i = 0.33 A

Step-by-step explanation:

As per ohm's law we know that voltage across any ohmic resistor is product of resistance and current through it

So it is given as

`V = i R`

now we know that

V = 120 Volts

R = 360 ohm

so here we have

`120 = 360 * i`

`i = (1)/(3) A`

Answer 2

Presume we are looking for the current:

V = IR

120 = I*360

120/360 = I

1/3 = I

I = 1/3 = 0.333..

Current ≈ 0.33 Ampere.
