Electronics - Posted on 2015-04-01 by Alexander Schug

Atoms make up all matter around us. An atom consist of a nucleus which is made up by nuetrons and protons while electrons circle around the nucleus. Protons, Electrons, and Nuetrons all obtain a charge. Electrons are negatively charged, protons are positively charged, and nuetrons are nuetral. Electrons and Protons are attracted to eachother. If there are alot of electrons or protons than the attraction is stronger. If the atom has the same amount of protons as electrons than the atom is stable. An atom with more electrons than protons is negatively charged. Some electrons jump from one atom to another and if an atom loses an electron it is positively charged. Electrons look to balance out an atom so this mean electrons look to jump on to positively charged atoms. Electrons jumping from atom to atom developes a flow of electricity. The flow of electricity can be inconsistent and as it travels is loses its flow. A peice of matter that has alot more loosely attached electrons will be a better conductor. The opposite of a conductor is an insulator which doesn't allow the flow of electrons and can cause friction. How well you can conduct electricity is based off of the resistance in the object. Resistance is the measure of how much the object opposes the flow of electrons. The unit of measure for resistance is OHMS. Pathways have been made for the flow of electricty which are called electronic circuits. Inside of these circuits is usually a voltage which is the amount of electromotive force. A volt is a unit of measure that tells the difference in electromotive potential. This voltage has a current which is pretty much how fast the electrons are traveling. Current is measured in Amperes which is a measure for how much electric charge is passing at a certain point in a circuit per unit of time. That being said the three main measures of electricity is Voltage, Resistance, and Current. Getting back to the circuits there are two different kinds. Ones Analog and ones digital. Analog circuits carry a voltage and they can be either series or parallel. Series is a continuous flow through all the components your trying to send signal to and with parallel circuits each component gets its own equal signal. Digital circuits carry a binary code instead of voltages which is expressed in 1 or 0, 1 meaning positive charge and 0 meaning no charge. There are two types of main currents. ne is alternating and one is direct. In a direct current electicity flows in one direction and in alternating currents electricty flows in both directions. Atoms are everything and I am atoms.
