LEVELS OF UNDERSTANDING
How much do you need to know? To own a car you do not need to understand the details of internal combustion engines, but the details leak out : gasoline, oil, batteries To do electronics you don't need a degree in materials science or solid state physics, but the details sometimes leak out : voltage, current, Ohms Law, etc. This session and the next are what we think you'll need to know to begin to have an intuitive grasp over the field of electronics.

ELECTRICITY
Think of electricity flowing like water in a pipe The analogy to water is not perfect, but it helps. Electrons are present and quite moveable in every conductor. Electricity is the ordered flow of electrons in a conductor.

VOLTAGE AND CURRENT
Voltage is like water pressure Measured in Volts, V Current is like water volume Measured in Amps, A 1/1000th of an Amp is a milliamp – mA Power is Voltage x Current Measured in Watts, W 1/1000th of a Watt is a milliwatt ­ mW

RESISTANCE
Almost everything that conducts electricity has a resistance. It doesn’t conduct it perfectly. Resistance is measured in Ohms (Ω) 1000Ω = 1kΩ 1,000,000Ω = 1MΩ

    Btec L3 Essay Example

    Ans: Electricity is the movement of electrons. As long as electrons in an atom are balance and revolve precisely in orbit around their sun or atom nucleus there is no electron flow or electric current in a wire. These atoms are the smallest particle into which an element can be divided without losing its property. A single atom consists of three basic components: a Proton, a Neutron and an Electron. An atom is similar to a small solar system, so is the nucleus in the centre of an atom. Protons and neutrons are contained within the nucleus. Electrons orbit around the nucleus which could be similar to planets orbiting around the sun. As an electrician I will also be dealing with insulators. An insulator is any material that stops the flow of electrons examples are rubber, glass and plastic. Conductors are the opposite of and insulator they are material that easily allows electrons to flow, like cooper, gold and silver. A material that has high resistance has low conductivity, this means that it doesn’t conduct current easily; likewise a material that has high resistance has high conductivity. Resistance is measured in units called Ohms. There are types of electricity, one is static electricity. Static electricity is the charges that are fixed in place unlike electrons in wires with voltages potential with no electron flow. Opposite electrical charges always attract each other, so these particles with opposite charges will tend to move towards each other. Like electrical charges always repel.…

    Wire Coursework

    Electricity is conducted through a conductor, in this case wire, by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better conductor. The free electrons are given energy and as a result move and collide with neighbouring free electrons. This happens across the length of the wire and thus electricity is conducted. Resistance is the…

    physics lab report of Circuits

    This continuous movement of free electrons through the conductors of a circuit is called a current (I). Current is often referred to in terms of “flow. The force motivating electrons to "flow" in a circuit is called voltage, which is a specific measure of potential energy which is always relative between two points. When there is a certain voltage present within the circuit it means the measurement of how much potential energy exists to moves the electrons from one particular point in the circuit to another particular point. Free electrons tend to move through conductors with some degree of friction, or opposition to motion. This opposition to motion is more properly called resistance. The amount of current in a circuit depends on the amount of voltage available to motivate…

    Electricity Report

    Inside an atom there is a nucleus and electrons that orbit around it. In many metals, the atoms have electrons that can detach from the atom and move around. These are called free electrons. Most metals, gold, silver, copper, all have free electrons. These electrical “conductors” make it easy for electricity to flow through them because of these free electrons. Electricity needs these conductive materials to move from place to place and to get electricity to move requires an electrical generator.…

    Ohms Law

    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.…

    Statement Of Purpose In Electronics

    STATEMENT OF PURPOSE Can you ever think of the Earth without the Sun? Today, the same scenario can be applied to the field of Electronics as well. It is hard to imagine life without electronics. Electronics has geared up our living conditions and has become the most vital part of our life. The invention of Transistor at BELL laboratory in the year 1947 had revolutionized the field of electronics. And this small device became the heart of an electronic circuit, and in turn transformed the way we live, work and play. This makes electronics one of the most challenging fields as it not only fulfills the present day needs but also has the capability of changing the way humans will lead their lives in the future as well. The past century has opened…
