Finding voltage drop across 2k ohm resistor using voltage division

[pat666]

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

What does R_T stand for?

 

[pat666]

total of the other resistors

 

[SammyS]

You must have calculated R_T wrong.

I get the book answer.

 

[SammyS]

Don't forget the 5kΩ resistor.

 

[pat666]

can you tell me how please, I got 5k for Rt

 

[SammyS]

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 R_T, judging by the way you used R_T.
