Conductivity
Conductivity, abbreviated as \( \gamma \) (Greek symbol gamma) and \( \sigma \) (Greek symbol sigma), is the amount of current that a material can conduct. Depending on the material, the transfer rate will vary. Lower the resistance, higher the conductivity. Higher the resistance, lower the conductivity.
