Active generally means that there is a power source, such as a cooling fan.
Passive generally means that it does NOT use a power source, such as a heat sink and cooling fins that use rising air to cool.

The difference between active and passive monitoring sampling?

Active Sampling refers to the process of connecting sample collection media (i.e., thermal desorption tube) to a sampling train consisting of inert tubing and a sample pump operating at a know flow rate. Once activated, the sample pump draws air through the sample media, resulting in a know sample v (MORE)

What is the difference between passive and active transport?

Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Osmosis is an example o (MORE)

What are the differences between active and passive transport?

Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in f (MORE)

Difference between active and passive immunity?

Passive immunity involves the bodies defenses which do not change for different types of microbes. This would be like Natural Killer B cells which attack a wide variety of microbes. Active immunity involves your body becoming acclimated toward a bacteria or virus, such that future contact will spur (MORE)

What is a difference between passive and active agglutination?

The only difference between the two is with active agglutination you have a particulate Ag + Ab, since the Ag is particulate, large, when a complex is formed it is visable.

For a passi (MORE)

What is the difference between active and passive elements?

Passive elements don't require power from the supply to produce its effect on a signal. They derive the power of the input signal to perform its action. for example, a resistor doesn't require a separate supply to provide its action of resistance in a circuit. Where as in active elements there (MORE)

Difference between active and passive components?

ACTIVE COMPONENTS The components which produce the energy in the form of current or voltage are called as active components. Example:transistors etc,. PASSIVE COMPONENTS The components which stores the energy in the form of current or voltage are called as passive components. exampl (MORE)

Difference between active and passive elements?

Active components can deliver a finite amount of power for some finite amount of time period where passive components can not deliver finite amount of power for some finite amount of time.

What is the difference between passive and active pickups?

A guitar pickup uses a magnet and coil (either single or double) to generate a small electrical current when the strings are plucked. This creates a disruption in the magnetic field which is interpreted by the amplifier. This describes a "passive" pickup. The signal is sent this way.. Active pickup (MORE)

Difference between active and passive voice?

The simplest sentences are in the active voice: they follow the pattern subject-verb-object, such as "Jack kissed Jill".
