the required “output” by the elongation of Nano wires starting from size 5 nanometers between a zigzag electrode and substrate(solid or flexible) by the application of sonic waves or mechanical vibrations.. The application of tension i.e. stretching and straining of Nano wires results in the flow of electric charge. The Nano generator with optimization could produce as much as 4 watts per cubic centimeter based on a calculation for a single Nano wire.. Advantages of the Nano generators are small

of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That enabled out group to see the element in an excited state. The unknown element was lithium. This is known because if the color of the flame produced. The group I was in got mainly all the correct colored flames‚ but the few that were incorrect happened because the wire loop wasn’t completely clean and there was still residue from the other

without the need for wires and also maintaining network connectivity [2]. Less wiring means greater flexibility‚ increase efficiency‚ and reduce wiring costs. Handheld devices such as Personal Digital Assistants (PDA) and cell phones allow remote users to synchronize personal databases and provide access to network services such as wireless e-mail‚ web browsing‚ and internet services [3].

Step 3. Remove the insulation around the bulb wires (the leads) so you can expose the wire underneath you need to remove enough insulation so you can wrap the exposed wire around the nails. Step 4. Take one of the exposed wires and wrap it around the galvanized (zinc) nail. If the wire keeps slipping off‚ use some electrical tape or gator clips to keep it attached. Step 5.Wrap the other end of the wire around the copper nail. Step 6.When the second wire is attached to the copper nail‚ your bulb will

proportional to its cross-sectional area. All materials show some resistance‚ except for superconductors‚ which have a resistance of zero. There are three external factors that influence the resistance in a conductor. Thickness (cross sectional area of the wire)‚ length‚ and temperature all have some effect on the amount of resistance created in a conductor. The fourth factor is the conductivity of the material we are using. Some metals are just more electrically conductive than others. This however‚ is

At the point when a current is goes through the wire ‚round lines of power are delivered around the wire. Those flux lines go in a heading depicted by the left-hand standard. The lines of power of the magnet go from the N shaft to the S post You can see that on one side of the wire‚ the attractive lines of power are going the other way accordingly the wire‚ flux lines contradict the magnet’s flux line
