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

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.

Answer 2

Answer:

i = 0.33 A

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

$120 = 360 \times i$

$i = \frac{1}{3} A$
