Homework Help: Calculate the current in each resistor

  1. Feb 10, 2009 #1
    1. The problem statement, all variables and given/known data

    (a) Find the equivalent resistance between points a and b in Figure P18.5 (R = 15.0 ).
    (refer to physics.gif for parts a. and b.)

    (b)Calculate the current in each resistor if a potential difference of 34.0 V is applied between points a and b.

    A (4.00 resistor)
    A (7.00 resistor)
    A (15.0 resistor)
    A (9.00 resistor)

    2. Find the equivalent resistance of the circuit in Figure P18.6. (R1 = 16 , R2 = 13 )
    (refer to physics2.gif for this problem)


    2. Relevant equations

    V = IR



    3. The attempt at a solution

    Honestly, I have NO idea where to start.

    Re: Circuits

    You're missing a relevant equation. What is the equivalent resistance of two or more parallel resistors?

    R(eq) = ?
