Homework Help: Equivalent resistance

  1. Oct 17, 2005 #1
    Can two resistors in series be replaced by a single resistor and give an equivalent resistance to the circuit?

    If so , how must the single resistance be related to the two in series ?
    R=R1+R2 ? ?

    My answer is yes they can be replaced by a single equivalent resistance

    buthow must the single resistance be related to the two in series ?????

    will it be in series !?

    i mean do we use R=R1+R2? is this the answer ?

    Yes, that's the answer. But I don't understand this: "will it be in series !?" Will it be in series with what? If you're replacing the whole series by one resistor, no.

    yup that's right. [tex] R_e_q_u=R_1+R_2[/tex]

    mich_v87, I've merged your 2 identical questions. Could you please refrain from doing so in the future (except for accidental posting) ?
