This was a question on the ISA T23 pre and post instructional survey where the answers are wrong.
After doing the math I wanted to cross check it here.
Values for pen and paper:
R1 : 2K OHMS
R2 : 2K OHMS
R3 : 5K OHMS
R4 : 2K OHMS
R5 : 4K OHMS
R6 : 7K OHMS
R7 : 100K OHMS
From top left to bottom
R1 & R2 in parallel, R3 in series with Parallel R1&R2.
R1, R2, and R3 in parallel with R4 Which is in series with R5.
R6 & R7 in series with the above
Questions:
What is Rtotal?
Voltage drop across R1?
Voltage drop across R4?
Voltage drop across R6?
Don't forget the your equivalent resistance calculation!
