A barometer measures the barometric pressure of the atmosphere. Units of millibars. That is one-thousanth of a bar. 0.001 bar equals a millibar.
A voltmeter measures electricities potential to do work measured in volts A.C. and D.C.. Most can also measure resistance in ohms and current in amps. Some can measure frequency (hertz= cycles per second) and capacitance in farads.
CommentIn SI, barometric pressure is measured in pascals (Pa).
Polarity
A voltmeter measures voltage in volts.
Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
A barometer measures atmospheric pressure. A voltmeter measures the difference in voltage between two points A wavelength has nothing to do with either of these measurements.

A barometer measures atmospheric pressure, which can indicate changes in weather patterns. A voltmeter measures electrical voltage and would not typically be used to measure environmental changes. To measure environmental changes, instruments such as thermometers, hygrometers, anemometers, or spectrophotometers would be more appropriate.

A thermometer and light meter are the most useful when measuring two environmental changes.
It was not used as a barometer.
Air pressure is measured with a barometer.
