Question

1-A lamp draws a current of 0.50 A when it is connected to a 120 V source.

a) What is the resistance of the lamp?

Answer 1

Hi there!

We can use Ohm's law to solve for the resistance of the lamp.

`V = IR`

V = Voltage (V)
I = Current (A)
R = Resistance (Ω)

We can rearrange to solve for resistance.

`R = (V)/(I)\\`

Plug in the given values:

`R = (120)/(0.5) = \boxed{240 \Omega}`
