A three-cell flashlight draws a current of 0.60A. What is the operating resistance of the light bulb if each cell provides a potential of 1.0V when delivering this current?
Homework Answers
here,
potential of each cell , V = 1 v
as there are three cell in series
Vnet = 3*V
vnet = 3 V
current , I = 0.6 A
the operating resistance of the light bulb , R = V/I
R = 3/0.6
R = 5 ohm
the operating resistance of the light bulb is 5 ohm
