Passive transducers - require an external power to operate, and the
output is a measure of some variation in passive components (e.g. resistance or
capacitance)
Examples of passive transducer :
-Slide-wire resistor
▫ Resistance strain gauge
▫ Differential transformer
Active Transducers - Self generating type - do not require an external power,
and produce an analog voltage or current when stimulated by some physical form of energy.
▫ Thermocouple
▫ Photovoltaic cell
▫ Moving coil generator
Thermocouple is one example. Photo voltaic cell
Solar Energy: Active- Using solar panels to warm house . Passive- Using windows ( or no machine.) Forced Air- When air is forced through air vents through out home. Electric- this method uses conduction to warm air around.
Turbine thrust bearing active and inactive temperature is the blade in the turbine trust bearing is actual temperature change, which mitigates the active or inactive bearing.
The pressure flow theory describes the movement of food through the phloem. The theory was originated by Ernst Munch.
A tamper switch (in a burglar alarm system for example) is designed to stop un-authorised access to the inside of the control panel. It usually takes the form of a small micro-switch that activated when the cover is opened. Even if the alarm has been de-activated (by entering the correct code) the anti-tamper circuit is still active so long as there is power to the system. Cutting the lead to the external sounder, or the mains lead doesn't stop it either - there is usually an internal sounder, and a back-up battery.
is a thermocouple an active or passive transducer?-why?
Yes, it's an active transducer. A thermocouple is passive not active
An example of a passive transducer is differential transformers. The reason why is because passive transducers require an external power supply to operate.
What is the difference between active attacks passive attacks in GSM network?
Active transport requires energy; passive transport does not.
The difference between a passive and an active dividend policy lies in the amount of time between dividend disbursement. In a passive dividend policy, dividends are given when the company decides it is time. With an active dividend policy, dividends are disbursed at regular intervals.

Passive voice is when the subject of a sentence is acted upon, while active voice is when the subject performs the action.
Passive language is when the subject of the sentence is being acted upon, while active language is when the subject is performing the action.
Passive tension is the force exerted on a muscle when it is stretched, while active tension is the force generated by the muscle when it contracts.
