EMT 1150 NOTES (ELECTRICAL CIRCUITS)
RESISTANCE
Conductance (G): An indication of the relative ease with which current can be established in a
material. It is measured in siemens (S).
Cooper effect: The “pairing” of electrons as they travel through a medium.
Ductility: The property of a material that allows it to be drawn into long, thin wires.
Inferred absolute temperature: The temperature through which a straight-line approximation
for the actual resistance-versustemperature curve intersects the temperature axis.
Malleability: The property of a material that allows it to be worked into many different shapes.
Negative temperature coefficient of resistance: The value revealing that the resistance of a
material will decrease with an increase in temperature.
Ohm: The unit of measurement applied to resistance.
Ohmmeter: An instrument for measuring resistance levels.
