Current with circuits

  1. Nov 10, 2004 #1
    Resistors R1 and R2 are connected in series to an emf source that has negligible internal resistance. What happens to the current through R1 when a third resistor R3 is added in parallel to R2?

    I think it will go up because the Req of R3 and R2 in parallel will be lower than R2. Since V=I*R, if R decreases, then I must increase. Is this true?

    Yes, that is true.
