A’ Group ‘B’ Group

1. Free electrons Weakly attached

2. Current V/ R

3. Resistivity VA/LI

4. Resistances in series Increases the resistance in the circuit

Free electrons are weakly attached .

Current = V/R (ohm law)

resistance = resistivity ×L/A

Resistivity = RA/L

R = V/I

resistivity = VA/LI

Resistance in series are added and increase the overall resistance.

while resistance i parallel decrease overall resistance.
