means that R1 , R2, and R3 are connected in parallel ... and the question contains no voltage value..sorry if it's vague.

Homework Statement If the circuit of parallel and series resistors , is as follows , what's the equivalent resistance for the group? Homework Equations neglecting the battery internal resistance... irrelevant to the question. The Attempt at a Solution I tried to do the following R1=8+12=20...
