Homework Help: How many appliances will melt aluminum wire?

  1. Jun 19, 2010 #1
    so i have to do a independent lab for physics which determines how many appliances will melt aluminum wire when in a circuit.

    i'm having trouble getting started with how to set everything up, does anyone know how i should go about it?

    Presumably the appliances are connected in parallel? How does each added appliance affect the total current drawn?

    One appliance will do it if the aluminum wire is thin enough.

    yes, it would be connected in a parallel circuit.
    wouldn't the current needed for each appliance add up to the total current needed (I=I1+I2+I3...)? so you would just need to find the current needed to melt a certain thickness of wire?

    That sounds reasonable to me.
