Rectifiers are made in various forms, all operating on the principle that current passes through them freely in one direction but only slightly or not at all in the opposite direction. One early type of rectifier was the diode electron tube electron tube, device consisting of a sealed enclosure in which electrons flow between electrodes separated either by a vacuum (in a vacuum tube) or by an ionized gas at low pressure (in a gas tube)......

Semiconductor semiconductor, solid material whose electrical conductivity at room temperature is between that of a conductor and that of an insulator (see conduction; insulation)...... Click the link for more information. rectifiers are essentially diodes diode , two-terminal electronic device that permits current flow predominantly in only one direction.

Rectifier rectifier [′rek·tə‚fī·ər] (electricity) Rectifier. Direct Current vs. Alternating Current" When you load a battery into an electronic device, you're not simply unleashing the electricity and sending it to do a task. Negatively charged electrons wish to travel to the positive portion of the battery -- and if they have to rev up your personal electric shaver along the way to get there, they'll do it. On a very simple level, it's much like water flowing down a stream and being forced to turn a water wheel to get from point A to point B.

Whether you are using a battery, a fuel cell or a solar cell to produce electricity, three things are always the same: The source of electricity must have two terminals: a positive terminal and a negative terminal.The source of electricity (whether it is a generator, battery or something else) will want to push electrons out of its negative terminal at a certain voltage. You can attach any type of load, such as a light bulb or motor, in the middle of the circuit. Direct Current (DC) Electricity - Succeed in Understanding Physics. SfC Home > Physics > Electricity > by Ron Kurtus (revised 11 January 2004) Direct current or DC electricity is the continuous movement of electrons from an area of negative (−) charges to an area of positive (+) charges through a conducting material such as a metal wire.

Whereas static electricity sparks consist of the sudden movement of electrons from a negative to positive surface, DC electricity is the continuous movement of the electrons through a wire. A DC circuit is necessary to allow the current or steam of electrons to flow. Such a circuit consists of a source of electric energy (such as a battery) and a conducting wire running from the positive end of the source to the negative terminal. Questions you may have include: What is DC electricity? This lesson will answer those questions. Continuous movement of electrons DC electricity is the continuous movement of electrons through a conducting material such as a metal wire.
