Homework Statement


see attached for circuit

from your result from part b, use voltage division to find the voltage drop across the 2k ohm resistor. my result from b was 250V

part b question was voltage drop across 10K resistor

Homework Equations





The Attempt at a Solution


R_T=5k ohms

v=V_2k/V_T = 100v but the answer is 50V?????

Thanks

You must have calculated RT wrong.

I get the book answer.

The 6kΩ, 18kΩ, and 9kΩ resistors are all in parallel with each other.

That combination is in series with the 5 kΩ and 2 kΩ resistors.

The above is what I would call RT, judging by the way you used RT.
