All the resistors are in ohms. I need to work out the current and power. enter image description here

    $\begingroup$ This is much simpler than the duplicate question because all the resistors are equal. Redraw it like a Wheatstone bridge network with the "middle" resistor rotated through 90 degrees and it is obvious by symmetry that there is no current through it. So you can remove that resistor, and the circuit is then trivial to solve. $\endgroup$ – alephzero Sep 17 at 18:42
