    Hi everyone,

    This is the first course in electronics I'm taking, so I apologize in advance for any wrong terms being used.

    I was wondering how to go about building the following circuit <see attachment >on a breadboard.


    1. How to place the resistances in parallel.
    2. I've noticed that capacitors have one "leg" longer than the other. Does this influence how I should position them on the breadboard?

    Thanks in advance for any answers or tips.
    If you have any references you think I should check out (links, textbooks) I'd be glad to have them!

    The long leg of a capacitor goes toward the more positive dc voltage.

    As for the breadboard, I have no quick way to draw a picture. There is generally one or two rows of holes distinct from the others. Put the ground in one hole and the whole row sees that voltage. You use these for your supply. All the other holes are hooked together in columns. Use an ohmmeter and you can figure it out.
