Circuit Problem

  1. Apr 2, 2009 #1
    1. The problem statement, all variables and given/known data

    This is the circuit in question. # 31. R1-R3 = 2 Ohms R4=16Ohms R5= 8 Ohms
    R6=4Ohms i6=1.4Amps

    2. Relevant equations

    V=i*R

    3. The attempt at a solution

    I see R5 and R6 as being in series, therefore r5*i6=11.2V
    r6*i6=5.6V

    Then I add them together=16.8V

    Since I see the rest of the circuit in Parralel the voltages should be equal to one another so I take 16.8*3=50.4V

    The back of the book says 48.3V


    Any idea on what concept I may be missing?

    Thank You very much in advance.

    Use branch current formula. If R1 and R2 are in parallel connection with I1 and I2 current, total current = I1 + I2. Then I1 = IR2/(R1 + R2)
    Use this formula for each loop and solve for E.
