    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.

    Measurements of voltage, current, charge, resistance, inductance, capacitance, phase angle, frequency, power and energy. Magnetic measurements.

    What value does it measure? The average torque produced in a dynamometer type wattmeter is proportional to a the average value ofcurrents in the two coils b the r. How does the damping torque act in these instruments? How is it prevented?

    What is CDRX? Derive the expression of damping torque produced in a metal former of PMMC instrument. In which way a ballistic galvanometer is different from common D'Arsonval galvanometer?

    How is the error due to temperature variation compensated in PMMC instruments? Describe the basic principle of Moving lron Ml instruments alongwith the torque equation. What is the condition for having a linear scale in MI instruments? Goodreads helps you keep track of books you want to read.
