• Ohm – Unit for resistance

• Circular Wires

• Circular mils

• 1000 mils = 1 inch

• Malleability- property of a metal to be

deformed by compression without cracking or

rupturing.

• Ductility- In a tensile test, ductile metals show

considerable elongation eventually failing by

necking, with consequent rapid increase in

local stresses

Types of resistors

 Fixed

 Variable

 Potentiometer

• Three legs
• Changes Voltage

 Rheostat

• Two legs
• Changes Current

 Resistor Color Code  0 – Black  1 - Brown  2 – Red  3 – Orange  4 - Yellow  5 – Green  6 – Blue  7 – Violet  8 – Gray  9 – White
