Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's laws) is the difference in electric potential energy between two points per unit electric charge.

The voltage between two points is equal to the work done per unit of charge against a static electric field to move the test charge between two points.

This is measured in units of volts (a joule per coulomb).

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role.

Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies.

Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

An analog signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal.

For example, in an analog audio signal, the instantaneous voltage of the signal varies continuously with the pressure of the sound waves.

It differs from a digital signal, in which the continuous quantity is a representation of a sequence of discrete values which can only take on one of a finite number of values.

The term analog signal usually refers to electrical signals; however, mechanical, pneumatic, hydraulic, human speech, and other systems may also convey or be considered analog signals.

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.

Humidity is the amount of water vapor present in the air.

Water vapor is the gaseous state of water and is invisible.

Humidity indicates the likelihood of precipitation, dew, or fog.

Higher humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin.

This effect is calculated in a heat index table or humidex.

The amount of water vapor that is needed to achieve saturation increases as the temperature increases.

As the temperature of a parcel of water becomes lower it will eventually not reach the point of saturation without adding or losing water mass.

The differences in the amount of water vapor in a parcel of air can be quite large.

For example, a parcel of air that is near saturation may contain 28 grams of water per cubic meter of air at 30 °C, but only 8 grams of water per cubic meter of air at 8 °C.
