    What is the Equivalent Resistance in a Series Circuit?

    Yes but i don't know how is it connected the R1,and how to find the eq reasistance of this circuit can u help me :/ .

    What is the Equivalent Resistance in a Series Circuit?

    R2,R3 are connected in series.And R4 R1 in paralel?

    What is the Equivalent Resistance in a Series Circuit?

    Then I did it so:R23=2Ω +2Ω =4Ω and 1/Re=1/4Ω + 1/2Ω +1/2Ω = 5/4Ω Re=4Ω /5? Is this the right way of slowing it?

    What is the Equivalent Resistance in a Series Circuit?

    Hi guys,I'm new here and maybe I'm posting this homework in a wrong part of the forum.I tried to find the equivalent resistance.It may be a simple homework but I am learning first for the electricy physic.I tried to find Re first R2+R3=4 Ω and than found Re=1/4 Ω + 1/2 Ω + 1/2 Ω can i slove it...

    The distance between 2 spheres in pendulum

    Hi guys,first nice to meet you I am new here.Im working on a physics homework and i.ve already done it but i don't know why the x=2lsinx ( x=distance between 2 spheres in pendulum). (P.S sorry for my bad english,im from Germany). Is that from a trig identity? I think I've understand it but if...
