A light bulb connected to a 9-V battery has a current of 1.5 A flowing.
a. Find the resistance of the light bulb (in ohms)
b. Find the power drawn by the light bulb (in W)
a. Find the resistance of the light bulb (in ohms)
b. Find the power drawn by the light bulb (in W)
a r=9/1.5
b. power=9*1.5
b. power=9*1.5
