We look forward to hearing from you!
Image source Amazon One of the popular members in the 74XXXYY IC series is the 74LS00 NAND Gate. Like most members of this logic gate, it does not operate independently. Instead, it is part of larger circuits that are used for complex tasks and operations. In most cases, it forms part of the integrated circuits…
Extension cord source Home advisor Are you planning to install an air conditioner? One of the accessories that you will need is a proper extension cord. The key feature of the extension cord is its gauge or size. So, what is the ideal gauge extension cord for an AC? The ideal extension cord for the…
Image source Mechanic base A blower motor resistor is an integral part of your vehicle’s heating and air conditioning system. A blower motor is responsible for determining the speed at which the fan rotates. All this happens due to the behavior of the resistor as it influences the rotation speed of the blower motor, onto…
Image source Amazon The 1N4001 is a popular general-purpose rectifier diode that has established its dominance in the electronics market. It is used in a wide range of applications ranging from the power supply systems to signal processing devices. The small size and low cost are among the key motivating factors behind the popularity of…
Image source Amazon Electromagnetic interference is a major issue in most electronic applications. It is likely to interfere with the transmission of signals and the flow of current. Think of devices such as phones computers and radios. These are just some of the electronic devices known to generate electromagnetic waves within their systems. Different devices…
We all know what a resistor does in an electric circuit. It is a component responsible for limiting or resisting the flow of electric current. There are various situations when you don’t want current to flow in a particular direction or through a specific section of a circuit. A resistor will come in handy. Resistors…
Camshaft sensor source: CarTreatmements A camshaft is a key component of a car’s engine. So, a camshaft position sensor (CMP) is type of device designed to monitor the exact position of a camshaft internal combustion engine. The position is measured with reference to the position of a crankshaft-another key component of an engine. This information…
Boost converter image source Wiki We have two keywords to think of: ‘Boost’ and ‘Converter’. A boost converter, also known as a step-up converter, is an electric device or circuit that converts DC-DC while simultaneously increasing the circuit’s voltage output. So, this is not an AC-DC converter as most electric converters do. Boost converters are…
100 amp panel source Spruce A panel box or service panel or distribution board is usually considered to be the housing for the circuit breakers. These panels are rated according to their amp capacities or amperage. You can have a 100 amp panel, 200 amp panel, or 300 amp panel, and many other options. In this…
Image of electric furnace source Provincial Heating After buying a furnace and preparing to install it, the next thing that you need to think of is buying the right circuit breaker. Which is the perfect breaker size for a furnace? In all cases, it will always depend on the electrical load of the furnace. The…
