Combination instruments[ edit ] Multimeter , combines the functions of ammeter, voltmeter and ohmmeter as a minimum. LCR meter , combines the functions of ohmmeter, capacitance meter and inductance meter. Also called component bridge due to the bridge circuit method of measurement. Thermodynamics [ edit ] Temperature -related considerations dominate thermodynamics. There are two distinct thermal properties: A thermal potential — the temperature. For example: A glowing coal has a different thermal quality than a non-glowing one. And a substance-like property, — the entropy ; for example: One glowing coal won't heat a pot of water, but a hundred will. Energy in thermodynamics is calculated by multipying the thermal potential by the amount of entropy found at that potential: temperature times entropy. Entropy can be created by friction but not annihilated. Amount of substance or mole number [ edit ] A physical quantity introduced in chemistry ; usually determined indirectly.
