A substance that can conduct electricity is called theconductorand a substance that cannot conduct electricity is known as the insulator. Semiconductors have properties that sit between the conductor and insulator. Adiode, integrated circuit (IC) andtransistorare all made from semiconductors. Theconducta...
A blocking diode is a diode placed in an electrical circuit for the purpose of preventing electrical current from flowing in a specific direction. By function, all diodes block electrical current; however, blocking diodes are used specifically to prevent a reverse flow of electrical power in order...
Inputs are used to get information about what is happening in the real world. For example, you can check if the button is pushed or not by using thedigitalRead()command. Or you can check the temperature in the room by connecting a temperature sensor and using theanalogRead()command. By c...
A diode has two terminals known as anode and cathode. The anode is indicated in a circuit diagram (refer to the lead image at the top of the blog) by the arrowhead, whereas the cathode forms the other end. Whenever the anode voltage is more positive than the cathode voltage, the diode ...
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 one direction while blocking it in the opposite ...
These diodes are known as photovoltaic cells and are the basis for solar electric energy systems and photosensors. Yet another form of diode, commonly used in electronic and computer equipment, emits visible light or infrared energy when current passes through it. Such a device is the familiar ...
A diode is a semiconductor device that has two terminals, an anode and a cathode, and allows current to flow only in one direction (from the anode to the cathode, known as the forward direction). Current does not flow in the reverse direction, except for special cases, such as when a ...
in modern technology, as they form the basis of electronic devices such as transistors, diodes, and integrated circuits. They're used in everything from microchips and processors to solar panels and LED lights. Understanding how semiconductors work is critical for anyone interested i...
The diode used in the circuit shown in the figure has a constant voltage drop of 0.5 V at all currents and a maximum power rating of 100 mW. What should be the value of the resistor R, connected in series with the diode for obtaining maximum current is
Fortunately, the Fluke 87V Industrial Multimeter has a built-in diode test mode, so that technicians can identify the defective LED and fix the problem quickly. The process consists of just four steps: Verify that all power to the circuit is off and that all capacitors are discharged. Set th...
