If you have two light bulbs in a Parrallel setup.
What will happen to the second light bulb if the first bulb is removed?
It will stay lit
What is the formula used in OHMs law?
(any of the three Will do)
V = I * R
I = V / R
R = V / I
open and close.
Draw a a circuit with a cell/ Battery and two light bulbs in series setup.
Draw a a circuit with a cell/ Battery and two light bulbs in parallel.
Using the formula R = V ÷ I.
Calculate the resistance in a circuit with a Voltage of 6 Volts and a current of 2 A.
(Double points if you include working and Units)
R = V ÷ I
R = 6V ÷ 2A
R = 3Ω
