Calculating Total Resistance in a Circuit - Tips and Tricks

[evanbarwise]

I'm wondering how to work out total resitance of a curcuit. The curcuit is made up of Kilo ohms.

25k Ohms
15k Ohms
50k Ohms
40k Ohms
20k Ohms

+ 10 V

I forgot to add that 50k Ohms is parallel to 40k and 20k Ohms.

it IS actually possible to give description of a circuit in such a way that we don't need
a picture, but you need to work a bit harder to make it unambiguous.
Something like:

The positive terminal of the battery is connected to termial 1 of R1
Terminal 2 of R1 is connected to terminal 1 of R2
Terminal 2 of R2 is conected to terminal 1 of R3 and terminal 1 of R4
etc.
R1 = 25kOhm, R2=15kOhm etc.

Or you can post or link to a picture
