Making a Potato Powered Light Bulb Materials: A large potato Two pennies Two zinc-plated nails or screws Three pieces of copper wire A very small light bulb or LED light 1) Get a potato and cut it in half. Then make a small slit in each half just big enough to put a penny into. 2) Cut two pieces of copper wire and wrap one around one of the pennies a few times‚ and wrap the other one around the other penny a few times as well. 3) Take a third piece of copper

A schematic of a typical fuel cell is shown in “Fig. 1”. Two electrodes are separated by a semi-permeable membrane and placed into solution. A biological species like an enzyme or microbial cell can either be in solution (or a suspension) within the anodic compartment of the cell or alternatively be immobilised at the electrode. Once a suitable fuel is introduced‚ it is oxidised at the anode partially or totally and the electrons released by

Intra-body Communication using Personal Area Network Abstract Intra-body communication is a "wireless" communication technique that enables electronic devices on or near the human body to exchange the information. For this the characteristics of the human body are studied. The human body acts as a signal transmission medium and it uses the dielectric properties of human tissues for data exchange which covers frequency range from 100 KHz to 150MHz. Transmitting data directly through the skin can

2012/2013 QUESTION 1 [10 marks] A high voltage assembly consists of two concentric spherical electrodes; aligned at the same center point. The inner electrode has a radius r1 whereas the outer electrode‚ r2. The voltage difference between the two electrodes is denoted as V. Using Gauss’s theorem and electrostatic principle‚ derive the expression for field enhancement factor of this electrode configuration.

reduces the contribution of non-frontal sources to frontal asymmetry and provides a better index of individual differences in the frontal asymmetry. The CSD however also comes with some limitations‚ more electrodes are needed for its estimation and its heightens the difference between electrodes which leads to the filtering out of small active patches of cortex between the

Anything made of metal‚ no matter how big or small‚ can be welded. Examples are everywhere‚ from vehicles like cars‚ trucks and motorcycles to rail cars‚ ships‚ aircraft‚ rockets and space stations. Construction is a huge market‚ and skyscrapers‚ bridges and highways would be impossible to build without welding‚ as would oil and natural-gas pipelines‚ offshore oil platforms‚ giant wind turbines and solar panels. Welders help install and maintain boilers‚ antipollution systems and other large structures

1. Introduction 22 Diabetes mellitus is the 7th leading cause of death in US. Diabetes is broadly classified into two 23 types: type I and type II. Type I diabetes is a result of insufficient insulin production by pancreas‚ 24 whereas type II diabetes is due to the body’s inability to use the insulin that is produced‚ hence the 25 name insulin resistance is used to refer to type II diabetes. Currently‚ individuals with diabetes are 26 able to monitor their blood glucose levels using a glucometer

ABSTRACT The experiment deals with determining the standard reduction potentials of different electrochemical half-cells through pairing it with Cu2+(0.1 M)|Cu half-cell and then comparing it with the theoretical value. Galvanic or voltaic cells contain the anodic and cathodic cell reactions‚ and in order to get the value of Ecell‚ we add both half-reactions. The more positive the Ecell‚the more negative ΔG would be‚ thus‚ giving us a spontaneous reaction. After comparing the cell potentials
