Homework Help: Circuit problem for resistors

  1. Sep 20, 2010 #1
    Hi:) I was wondering if anyone could help me?

    I need to find:
    The resistor total, the current supplied by the battery, and the current through resistor R2.

    R1: 3
    R2: 7
    R3: 12
    R4: 10
    emf: 6 volts

    I found the current through resistor R1 by taking 6v/3= 2 amps

    Thank you:)

    your diagram is to pixelated to see which resistor is which but I always found the most useful thing for solving problems like this to be redrawing the diagram in an easier to understand way. check my pic it shold be the same circuit as yours but easier to understand. treat the whole middle group as one resistor initially and find the voltage and current through it - then break it down...... hope this helps!
