    Small Piezoelectric Application, will it work?

    I am planning to do a small project based on piezoelectric effect. The idea is to sandwich a piezoelectric crystal in-between metal plates and use it as a school bell or a small calling bell. I am planning to use a battery (need not be full, which holds charge enough to ring the bell for the...

    Measurement of voltage and current

    That is fine. But the thing which worries me is the cost. Approximately how much will it cost to step down 230 KV to 5 V.

    Measurement of voltage and current

    Aren't potential transformer extremely costly. And will they be able to step down 230 KV to a mere 5 V.

    Measurement of voltage and current

    Ah! that shows my ignorance. I meant the low voltage wave must vary in accordance with the high voltage wave.

    Measurement of voltage and current

    I was trying to make a paper on synchronizing alternators. If I can monitor the amplitude phase and frequency of two generators, then I thought that I could synchronize them using a differential amplifier or a simple logic gate. For amplifiers and gate to work I wanted a low voltage waveform...

    Measurement of voltage and current

    Is there a way in electrical engineering where I can convert 230 KV to 5 V such that the 5 V wave has same amplitude, phase and frequency as that of 230 KV.

    Application of piezo-electric effect

    Can I use the piezo-electric crystal to charge a small battery and connect the battery to a load. The problem here is that the battery has to supply current to the load for a short period. Then it has to be recharged by the crystal. will I be able to use the same battery for charging and...

    Conversion of Light energy to Sound energy

    Is there a way to convert light energy to a sound energy? I read an article and the URL is http://www.photonics.com/Article.aspx?AID=52646 It is described that nano material lenses are used. Is there a much simpler way that I convert light to sound?

    Energy Distribution in Wheel - Can Multiple Dynamos Increase Output Power?

    I still have a doubt. Assume a bus is moving at some speed. A small generator is connected on one side of a wheel. W watt of power is obtained. If another generator is connected on the other side of the same wheel would the output be the same W watt. Assume that the mechanical input is x when...

    Energy Distribution in Wheel - Can Multiple Dynamos Increase Output Power?

    Recently I heard about using exercise bikes to generate electricity. It is more or less like a bi-cycle fixed in a training stand. They convert the rotation of the wheel into electrical energy. The scenario is that they take some W watt of power from that model. In their case a disc like...

    Maximum Vibrations in a material

    I am not exactly sure. But, Assume that the material I want to sustain vibrations is A. A is sandwiched between an another material B. I initiate the process by striking B, so that the vibrations are transferred to A. I do this because when I directly strike A, Vibrations induces is very less...

    Maximum Vibrations in a material

    I just want to transfer the vibrations produced from a material to another material. Like for example, I want to sandwich a material in between two vibrating material so that the vibration is transferred or sustained in the material which is placed in the middle.

    Big Town Clock or Tower clock

    Thanks for the reply. I am still not sure how a town clock works. May be you can come to a conclusion after watching these links. do we need to give a key to it manually every once in a while?

    Big Town Clock or Tower clock

    I just wanted to know how a town or a tower clock works. I would like to know if I can device a mechanism such that I will be able to use the striking train to strike every second, loud and clear i.e. I must get a loud chime every second but without using an electrical supply.

    Maximum Vibrations in a material

    For example, if I strike a copper or silver materials with each other they produce vibrations or even when a string is stretched in a guitar vibrations are produced. Likewise which material induces maximum vibrations for a sustained period of time?
