    Hi. The file attached is a circuit I found on the internet that should perform the OR operation.
    My question is how should I simulate this using MULTISIM?What voltage value should I use in the inputs and where will I put the indicator lamp to indicate whether the output is logic 1 or 0?
    This is the first time I will be using a software to simulate a circuit.

    I assume you will put the LED and series resistor on the output.

    As far as input ... use logic levels.

    MultiSIM has Logic gates. In MultiSIM 9 & 10 it's under misc. digital. Just use an OR2. (2 input OR Gate). Or if you want to use the circuit you provided, then either way I would do this:

    Vcc = 5 V
    use SPST switches at inputs (closed is High, open is Low)
    under a section called indicators is something called a probe. Pick a color and put this at the output. Probe ON is high, Probe OFF is low.
