How Does an Inductor Work?

Simply put, an inductor is a coil of wire wrapped around a core, which could be air or a magnet. As current moves through the inductor, a magnetic field starts to form, which the inductor uses to store energy. Inductors, along with capacitors and resistors, are essential electronic components. They’re used in a variety of… Read more »

How to Tell Positive and Negative on a Capacitor

There are different types of capacitors, but only one type is polarized: the electrolytic capacitor. Compared to non-polarized capacitors, electrolytic capacitors are more expensive and have to be installed in a specific direction to function properly, but they have higher capacitance — or the ability to hold more charge. Read on to find out how to… Read more »

How to Calculate Capacitance

To learn how to calculate capacitance, you must first know the answer to the question, “What is capacitance?” Capacitance is the measure of a capacitor’s ability to store charge. This ability is measured in units called farads, named after Michael Faraday. However, many of the devices used in electronic circuits hold capacitors with capacitance that… Read more »

What is Electrostatic Discharge?

Electrostatic discharge (also known as ESD) is a sudden burst of electricity created between two electrically charged components. ESD is caused by either static electricity or electrostatic induction, and occurs either when oppositely charged objects come together or experience a dielectric break. While ESD can create sparks, it oftentimes takes place without visual or audible… Read more »

What is a Twisted Pair Cable?

A twisted pair cable is created by taking two different insulated wires and twisting them together, allowing them to run parallel to each other in a pattern. This type of cable can be either a shielded twisted pair cable (STP) or unshielded twisted pair cable (UTP), and while they each exhibit a unique design, both… Read more »

How to Test a Relay

A starter relay, also known as a starter solenoid, is an electromagnet within a car’s internal combustion engine, used to help start the motor. Because this part is such a crucial element for connecting battery power to the starter motor, it’s important to understand how to test a starter relay when issues arise. Discover the… Read more »

What is a Terminal Block?

A terminal block is tool used to safely connect two or more wires together. Also known as a terminal block connector, these blocks use a clamping component and conducting strip to secure and organize connecting wires. A terminal block allows users to join multiple outgoing wires to one singular incoming wire, thanks to its insulated… Read more »

How to Test a Thermistor

Thermistors are used to measure changes in temperature and deliver changes in electrical resistance in response. Because these thermally sensitive resistors aim to maintain an absolute temperature for electronics and machinery, it is vital to ensure they are working properly at all times. Learn about how testing a thermistor can keep your electronics running at… Read more »

What is ESS Testing?

An ESS test evaluates whether electronic products have any defects or malfunctioning components. ESS stands for “environmental stress screening,” and is commonly used for military technology rather than commercial products. While the tests themselves are not particularly complicated, they help weed out flaws and avoid any potential failures during future product use. Request a Quote… Read more »

What is a Thermistor?

Thermistor comes from “thermally sensitive resistor,” which was the original name of these devices. Thermistors are resistance thermometers and a type of semiconductor that have an electrical resistance that changes depending on the weather. They have a low resistance to insulation but a higher resistance to conduction. Thermistors are made of metallic oxides that are… Read more »

How to Terminate Coax Cable

Coaxial cables are used to transmit cable, internet, and audio signals, connecting transmitters and receivers with their respective networks. With these easy coax cable termination instructions, you can save money by making your own cables in a few simple steps.

What is a Slave Cable?

Slave cables are used to jump start military vehicles with dead batteries. Outside of military use, they are more commonly referred to as jumper cables, and provide a fast, easy, vehicle-to-vehicle boost of power to get back on the road. A majority of US military vehicles are outfitted with a NATO receptacle, meaning that that… Read more »
