Presentation Transcript

  1. Calculate the cross-sectional area of a wire of diameter of 1.0 mm (In m2 of course!)

  2. Resistivity

  3. Contacts on switches, transistors, heating elements, (insulating) dielectric for capacitors, lamp filament

  4. Try this one! What length of constantan wire of diameter 0.40mm has a resistance of 10.0Ω ? Assume that the resistivity of constantan is 5.0 x 10-7 Ωm Hints: Work out cross-sectional area first in m2 ! Show ALL of your working.
