The Works of An Electrical Circuit

By Edwin A Sandiford

In electrical circuits, electricity flows through wires, resistors, and switches. Resistors can be added on to each other and it depends on its positioning in order to get added resistance. This includes parallel resistors and in series. The resistors lower the amps or current that flows through a circuit so that the wire or any other thing get burned out. Every circuit composed of a power source, some thing to conduct the current, and at times a resistor. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component. In a series circuit, the current through each of the components is the same, and the voltage across the components is the sum of the voltages across each component. his includes parallel resistors and in series. The resistors lower the amps or current that flows through a circuit so that the wire or any other thing get burned out. Voltage is the force and is measured in volts (V). A typical flashlight battery produces 1.5 volts, and the standard household electrical voltage up to 250 volts.

In an incandescent bulb, the current flows through a thin tungsten wire or a metallic filament that offers high resistance to current flow. When the electrons bump into the atoms, the friction, or loss of kinetic energy, produces heat. If the temperature of the filament is high enough, it starts to glow and give off light. This is incandescence. Typical filament temperatures for light bulbs are around 4,600 degrees. Unfortunately, 90 to 95 percent of the energy supplied to a light bulb is lost in the form of heat rather than light, so incandescent bulbs are very inefficient. �Fluorescent lights produce light by having electrons pass through a tube filled with mercury vapor and neon or argon gas. As the electrons bump into the mercury atoms, they cause electrons in the atoms to absorb some of their energy. As these electrons return to their normal state, they radiate bundles of light energy called photons. Fluorescent lights are four to five times more efficient than incandescent bulbs.

This is how an electrical circuit works including all off its various functions and parts that are needed to complete one. In conclusion there are specific ways to creating a circuit correctly to conduct electricity.
