Resistance:
Resistance is the property of a material to oppose the flow of electric current. It is measured in units of ohms (Ω).
Specific Resistance:
Specific resistance is the resistance of a material per unit of length and cross-sectional area. It is also known as resistivity and is measured in ohm-meters (Ω•m).
Conductance:
Conductance is the reciprocal of resistance and measures the ease with which an electric current can pass through a material. It is measured in units of Siemens (S).
