Electroencephalography (EEG) is used to monitor and test electrical activity in the brain. The first EEG was developed in the 1920s by Hans Berger‚ which was first used in 1924 to assess electrical current in the brain. Electroencephalography is conducted when electrodes are placed and attached to the scalp;

Procedure: We insert copper and zinc electrodes into the potato‚ close but not touching each other. We use alligator clip leads to connect our electrodes to the Multi-meter to measure voltage between two electrodes or current passing through the multi-meter. We

There are a few methods to extract metals from its ores. The main ones are electrolysis (the decomposition of a compound using electricity) and heating with carbon or carbon monoxide (or called the “Blast Furnace”). Some other metals like Silver and Gold occur naturally in the Earth’s crust as “native metals”. The method to extract the metal depends on its place in the Reactivity Series (how reactive the metal is). The more reactive the metal‚ the more difficult it is to extract. Thus electrolysis

It is shown that there is the possibility to unsqueeze electron packet in the transverse direction to macroscopic size by scattering on such electrode. Experiment on observing of such macroscopic packet on the luminophore screen is discussed. Keywords: electronic emission‚ vacuum photodetectors‚ photocounts

The next part is to determine the molarity of acetic acid and mass percent in vinegar where the vinegar is diluted as the same way in previous part. The titration is repeated

PHY124- C1 date performed: 5/22/13 Rousselle Molina date submitted: 5/29/13 ELECTRIC FIELD MAPPING I. ABSTRACT: In the Electric Field Mapping‚ we used charged electrodes to create an electric field on a glass tray with a piece of linear graph paper attached to the bottom. We tested several simple electrode positions by moving the probes and drew equipotential lines based on the voltage difference. We then confirmed that the equipotential lines run perpendicular to electric field
