“What is a diode?” A diode is a fundamental component that is at the very basics of many electronics projects. Unlike some of the passive components we’ve talked about recently (like resistors), a diode is a semiconductor. And as far as semiconductors go, one of the...
Diodes are two-port devices. There's a positive input, which is known as the anode, and there's a negative output, which is known the cathode (Figure 1). Figure 1. A diode's circuit symbol. The anode is on the left, and the cathode is on the right. Diodes may be simple, but ...
However, if the higher voltage is connected to the cathode, then the diode does not conduct electricity, and the process is called reverse bias. There are different types of diodes such as normal diodes, light-emitting diodes, zener diodes, Schottky diodes and photodiodes. The circuit symbol ...
Although the electricity that comes through the power lines is AC, electronics equipment often requires DC electricity. In a circuit diagram, the direct current symbol is a straight line with three dots or lines underneath it, while that for alternating current is a single wavy line. To convert...
Final Thoughts Though small and simple, the diode is an essential part of modern electrical systems. By controlling the flow and direction of current, diodes enable countless applications of modern electronics. Fortunately, tools like digital multimeters make it easy to measure diode health and determ...
Once the faulty diodes are identified, a technician can simply replace them, and the scoreboard should work like normal again. Final Thoughts Though small and simple, the diode is an essential part of modern electrical systems. By controlling the flow and direction of current, diodes enable count...
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength wh
The positive of the battery is tied to a point called ''net label'' and the negative of the battery is tied to circuit ground. When current flows from the battery through the resistor, the transistor will turn on. The transistor is the symbol just to the right of the resistor. ...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
symbol rectifier, it resembles an arrow pointing in the direction in which electricity can flow. In the context of electric currents, what do diodes do in a circuit - a diode is a semiconductor that is used to control the flow of electrical current in a circuit, allowing it to flow in ...
