Answer 1

Answer 2

Be careful with the S2 Open condition, note that the voltage is halved across each heating element (120 volts), Then remember that power is equal to (E^2)/R. You have erred in your calculations.

Answer 3

I have to run now, but will return this evening to see what you came up with.

Answer 4

Well done, your answers are all correct :))

Answer 5

I'm back, and as vincent-lyon.Fr has indicated you did take in the consideration of the voltage being reduced by 1/2 and that reducing the power by 1/4. Your table is correct and sorry that I thought you failed to take that into consideration. I am deleting my previous post.

Answer 6

Thanks a lot !
I hope you both have a wonderful day!! ^^
