Combination circuit resistance calculations

Hello all. I am working on a pre-lab for my DC circuits class and this question has me a bit stumped. I have been asked to calculate the following:
  • Resistance of BD
  • Resistance Total
  • Resistance of BC
  • Resistance of CD
I understand the series and parallel equations for resistance, but I am struggling with the flow of the current here. would it go in at A, then split at B, coming out at D and ending at E?

How would I find the resistance from B to D? From B to C? and from C to D?

I believe the total resistance would be 1,428.57Ω, with 628.57Ω coming from the middle section, and having 330Ω and 470Ω added to it. This may be incorrect but that is how I would think to do the total resistance.

Thank you in advance for any help that is offered.

hi,
Your over complicating it..;)
What do you calculate the Series sum of the 3.3k and the 1.2k to be.??

E

Hint: forget about the 330R and the 470R and the 2k2 for now..

OK, look at this breakdown of your circuit for doing BC

One resistor is in parallel with two resistors in series,

How would you solve this for BC,??

E
