compiled enough data to conclude that the mass of one of these particles‚ which he called an electron‚ was lighter than an atom of hydrogen by around 2‚000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.

interior of the neuron has a negative electrical charge that is parallel with the positive charge exterior of the cell. Ions‚ chemicals with too many or too few electrons per the number of protons thus making them positively or negatively charged‚ maintain the harmony of positive and negative charges. Calcium ions accommodate two positive charges. While Sodium and Potassium each embrace one positive charge. Chloride‚ on the other hand‚ contains a negative charge. When at rest‚ the cell membrane of the

with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects‚ such as lightning‚ static electricity‚ electromagnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. In electricity‚ charges produce electromagnetic fields which act on other charges. Electricity occurs because of the following‚ an electric charge‚ that is a property of some subatomic

Name: _____________________ Wire Resistance and Ohm’s Law PhET MiniLab Introduction: When an electrical potential exists in a circuit‚ a current may flow. Current is the flow of electrons in a circuit. Resistance in the circuit slows the flow of the electrons‚ reducing the current in the circuit. We will use the mathematical form of Ohm’s Law frequently when we investigate electric current and circuits later in this unit. • Open the PhET Simulation Electricity‚ Magnets‚ and Circuits ( Resistance

AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

ABSTRACT This study aims to make an improvised traveling charger that will use heat or waste heat to charge a battery. It is not new to us that we are lacking for the supply of the electricity and being in the modern times‚ we can’t live without cell phones and how does we able to charge the battery if there’s no supply of electricity. The researcher used scrap materials that can be easily found. They used copper and iron plate‚ some adhesives copper wires and the normal traveling charger to construct
