How to find current through resistors.

  1. Jun 21, 2011 #1
    1. The problem statement, all variables and given/known data
    Two resistors with R1 = 1755 omega and R2 = 4020 omega are connected in parallel. The battery emf is large epsilon = 15 V.

    What is the current through resistors R1?
    What is the current through resistors R2?

    2. Relevant equations

    3. The attempt at a solution
    I know I am somehow supposed to use V=Emf - Iresistance, but i dont feel like i have enough information. Do i just need to somehow find V and then plug it in? If so what formula do i use?

    In the parallel combination of the resistances, voltage across each resistance is same and is equal to the applied voltage. Use ohm's law to find the current in each resistance.
