    Hi Ashley Shaw. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif [Broken]

    Your original thread title of "Physics: Electromagnetism HELP!!!!!!" was hardly applicable. :eek:

    You've found a solution to this exact question. You can see they redrew the circuit, replacing two parallel resistors by a single resistor equivalent to those two in parallel.

    Current flows from node a to e and the magnitude of that current is 0.05A.

    Hints..

    Work out what the equivalent resistance is of a 4 Ohm in parallel with a 3Ohm.

    Then with reference to the reduced circuit...

    2.71R = 1.71R + R

    3.71R = 1.71R + 2R
