Automotive Fuse Link Definition and Specifications Automotive use links are self-acting break appliances for the protection of electrical devices against unsuitable current loads. The current flow is interrupted by the melting of the fuse wire in which the current flows. The following international regulations and recommendations in their currently valid version are valid for fuse links:.
Majority of street lights, outdoor lights, and a number of indoor home appliances are typically operated and maintained manually in many occasions. This is not only risky, however additionally it leads to wastage of power with the negligence of personnel or uncommon circumstances in controlling these electrical appliances ON and OFF. This article discusses in brief about what is a light dependent resistor, how to make a light dependent resistor circuit and its applications. An LDR or light dependent resistor is also known as photo resistor , photocell, photoconductor. It is a one type of resistor whose resistance varies depending on the amount of light falling on its surface. When the light falls on the resistor, then the resistance changes. These resistors are often used in many circuits where it is required to sense the presence of light.
Basics of Ceramic Chip Capacitors
Electronic gadgets have become an integral part of our lives. They have made our lives more comfortable and convenient. From aviation to medical and healthcare industries, electronic gadgets have a wide range of applications in the modern world.
Overheating then damages the resistive element, leading to a resistance change or even the opening of the device. To avoid this in your design, below are eleven things you should know about resistors and pulse loads when selecting a component:. For short pulses adiabatic condition , the heat remains in the resistive element but the shortness of the pulse limits its effect on the resistive element temperature, even for high pulse loads. Thus the resistor will withstand peak pulse loads higher than its rated dissipation. For long pulses, the prolonged heat generation causes a more significant temperature rise in the resistive element, although this will be limited by heat removal already setting in during the pulse. Hence, for extended pulse durations the permissible peak pulse load approaches rated dissipation. The difference between a single pulse load and a continuous pulse load is a function of the number of pulses and the time interval between them. Single Pulse Load: The time interval T between pulses is long enough to allow for cooling of the resistor between pulses. Continuous Pulse Load: The time interval T between pulses is short and prevents cooling of the resistor between pulses.
Top ten harsh environment resistors
Take a look at our top neuroscience stories from here. In the following article, we will look at how resistance and capacitance determine the electrical properties of the cell to understand why this is a useful description. The cell membrane consists of a double lipid layer that separates ions in the extracellular space from ions and charged proteins in the cytoplasm. While pure lipid membranes are excellent electrical insulators, real cell membranes consist of a dense mosaic of proteins and lipids. Many of these proteins span the membrane and act as channels that allow charge to pass. These proteins reduce the otherwise high resistance of the membrane, which has significant consequences for electrophysiology. Assume we want to apply a voltage across the cell membrane by injecting current with an electrode. We can see that the higher the membrane resistance, the lower the current required to maintain a given membrane voltage. Because the membrane is an electrical insulator separating opposing charges inside and outside the cell, the cell membrane not only has a resistance but also a membrane capacitance. Therefore, to change the membrane voltage, it is necessary to charge the capacitance.
11 things you need to know about resistors in pulse load applications
Film resistor technologies have come a long way since metalised glass and cracked carbon films were first offered over eighty years ago as alternatives to the bulk material approaches of wirewound and composition. Metal oxide emerged in the s as a more stable film and was widely applied until ceding ground to metal film for precision and thick film for high power uses. Both of these technologies were then employed in the emerging SMD chip format. However, it would be a mistake to think that nothing is changing in the world of film resistors. This paper identifies three drivers of continued evolution and outlines some of the developments which are being made in response. The first driver is imperative to reduce environmental impact and is felt through legislated regulation and, indirectly, consumer pressure. Following this is continued expansion of the safe operating area, pushing back on the electrical rating limits which constrain miniaturisation of analogue circuits.

Are you having trouble reading resistor color codes? If your answer is yes, then this tool is specifically designed for you! The resistance value is displayed on the field below together with the tolerance and the temperature coefficient. As shown above, a carbon-composition resistor can have 4 to 6 bands.
An electronic load is a type of instrument that applies a voltage and sinks current. Manufacturers of these types of products need to test their supplies dynamically, rapidly increasing and decreasing the load in a repeatable fashion, programmable electronic loads make this much easier than configuring resistors or resistive elements for each test.
