Thread:Nice work; minor changes (1)

Hi folks,

I made some small changes and I suggest some others:
 * Add the term insulator
 * Do you need insulated wire or does it matter?
 * Your vocab is inconsistent between the wiki and the handout; worth fixing
 * A closed loop is a circuit rather than a conductor (see handout)
 * Handout:
 * Terms are frame shifted
 * Roll not Role
 * suggestion: consider adding a foil reflector and electrical contact (the foil will grip both the bulb and the wire; but you'd need a cardboard disk with a hole in the center to prevent the foil from shorting out the flashlight)

More comments coming very soon
