Question #2: The circuit shown below has three loads in series, with the following resistances:
R1 = 10 ohms
R2 = 20 ohms
R3 = 40 ohms.
What is the total circuit resistance?
I added the resistance and it came to 70, do I divide 1\70 or do I do 70/1 to get my answer? Or do I take each of the resistances and divide each one of those by either 1/R or r/1 and than add them up and than divide?
