TRANSDUCERS Transducers are electric or electronic devices that transform energy from one form to another. A transducer is a device that converts one form of energy to other form. It converts the measureand to a usable electrical signal. In other word it is a device that is capable of converting the physical quantity into a proportional electrical quantity such as voltage or current. Industrial uses of transducers - Temperature‚ force‚ strain‚ liquid level‚ flow rate‚ electrical conductivity

WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above

A diode is a two-terminal device‚ having two active electrodes‚ between which it allows the transfer of current in one direction only. Diodes are known for their unidirectional current property‚ wherein‚ the electric current is allowed to flow in one direction. Basically‚ diodes are used for the purpose of rectifying waveforms‚ and can be used within power supplies or within radio detectors. They can also be used in circuits where ’one way’ effect of diode is required. Most diodes are made from semiconductors

They both were using a new technique called gravity assist to help maneuver. Voyager 1 and 2 are powered by radioisotope thermoelectric generators (RTG). The mission plan for Voyager 1 and 2 was to look at all the gas giants in the solar system they called this plan the grand tour‚ the planets include were Jupiter‚ Saturn‚ Uranus‚ and Neptune. Voyager 1 was the first spacecraft

screen. So how does this wonder phone work? This is a TFT capacitive touch screen phone and uses human body heat as electricity to charge the mobile phone. It’s based on the nanotechnology engineering using a micro device called thermoelectric device. The thermoelectric device is integrated with the glass surface and transmits energy to the battery whenever a user touches the phone screen using his/her hand. And in the process the phone starts charging itself. In short the more the user uses the

Micropower Energy Harvesting Abstract More than a decade of research in the field of thermal‚ motion‚ vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent energy harvesting results. Introduction The low power consumption of silicon-based electronics

1. How much of our global energy supply do nuclear power‚ biomass energy‚ and hydroelectric power contribute? How much of our global electricity do these three conventional energy alternatives generate? Biomass provides 10.8% of global primary energy use‚ nuclear power provides 6.5%‚ and hydropower provides 2.2% of global primary energy use. Nuclear power generates 15.8% of the world’s electricity‚ and hydropower generates 15.9%. 2. Describe how nuclear fission works. How do nuclear plant engineers

Many people may be wondering why is water so essential in life‚ there’s an endless reasons for the importance of water. To say a few would be‚ 75% of human body is composed of water; we need water for our daily basis such as bath‚ and water is widely used agriculturally‚ economically and commercially. But the most important reason of all is that water is required for life to occur‚ biological evidence furthermore support that the first sign of life begins with water‚ no water equals no life. Water
