if a current flowing through a lightbulb is 0.75 ampere and the voltage differences across the lightbulb is 120 volts how much resistance does the lightbulb have

Respuesta :

We have the equation I = V/R ( according to ohm’s law
==> R = V / I
==> R = 120/0.75
==> R = 160 ohms
*I is current ( unit : ampere)
*V is voltage different and R is resistance
