Conductivity of Metals helping you understand the types of conductivity metals

conductivity of metals will help the electrical engineering students identify the types of metal conductors in using electrify.

1. Conductivity of Metals

2. GOLD

3. SILVER

4. COPPER

5. Georg Simon Ohm Ohm’s Law V= IxR

6. Metal Conductivity Conductivity in metal is  a measure of a metal material's ability to transmit heat, or electricity (or sound) . Constant Siemens per meter (S⋅m −1 ) Greek letter sigma ( σ) .  One siemens is equal to the reciprocal of one ohm. Inducement offered by the conductor to the flow of current

7. Electrical Conductivity When we apply Voltage across a conductor, there will be a current flowing through it thus, with the same voltage and dimension, Current will not be the same for all Conductors. Conductivity is opposite of resistivity

8. Resistivity of Metals

9. Resistivity of Metals We measure how a material Resist the flow of current through a conductor. Resistivity, commonly symbolized by the  Greek letter rho, ρ , is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. The unit of resistance is the ohm.

10. Factors affecting resistivity of electric materials Length of the substance – First Law of Resistivity Cross sectional area – Second Law of Resistivity Nature of material ( Resistivity ) – Third Law of Resistivity Temperature – Fourth Law of Resistivity

11. Resistivity or Coefficient of Resistance Where: R = Resistance in ohms ( Ω ) ρ = Resistivity ( Ω .m) constant L = Length of a Material (meters) A = Cross sectional Area (square meters

12. Properties of Conducting Materials Conductivity Tensile Strength Ductility Corrosion Resistance
