CFM stands for cubic feet per minute. CFM is a volumetric unit of flow. CFM represents the maximum amount of air that a fan can move at maximum speed and without any restrictions. CFM is related to the fan’s motor (rotational speed), blade length, blade pitch and shape.

The majority of rechargeable AA and AAA batteries on the market are Nickel-metal hydride (NiMH) batteries. NiMH batteries can be charged/discharged for up to 500-1,000 cycles. This means they can be used for up to 10 years at an average charging frequency.

Electrical devices can consume energy even when we are not using them, causing our electricity bill to be high. So what are the effective ways that we can easily apply to reduce the electricity bill?

An oscillator is an electronic circuit or device that can convert a steady-state signal into an oscillating signal (sine wave signal). Oscillators are used to generate repetitive electronic signals. An oscillator can convert a steady-state DC signal into a periodic AC signal at a desired frequency.

Calibration is a documented comparison of a measuring device to a traceable reference device. Calibration refers to the process that enables measuring instruments to produce outputs that provide high levels of accuracy and precision. The main purpose of calibration is to ensure the accuracy of measuring instruments and to minimize...

LDR (photoresistor) and photodiode are two types of light sensors commonly used. When the LDR is exposed to light, its resistance changes. The photodiode, on the other hand, produces current when exposed to light. This is the main difference between LDR and photodiode.

Capacitors and supercapacitors are passive components that store energy in the form of an electrostatic field. Although the function of both is to store energy, there are some important differences between them. Supercapacitors can store more charge than regular capacitors and provide energy much faster than a battery.

Devices that can measure the temperature of objects remotely and quickly without any contact are called infrared thermometers. Infrared thermometers collect infrared light emitted from objects and estimate their temperature based on the amount of energy. These devices are frequently used in industrial applications as well as preferred by home...

Flux is a chemical used when soldering electronic components to a circuit board. The main purpose of flux is to prepare the surface for soldering by cleaning the oxide and foreign materials on the metal surfaces. Flux is used to clean the circuit board before soldering. During soldering, it helps...

Photocell and motion sensor are electronic devices used to manage indoor and outdoor lighting systems. These sensors are used to save energy by turning the lights on when it gets dark or when motion is detected, and turning them off when they are no longer needed.

Managing the heat generated by the components is very important in the design of electronic systems. High-power components generate more heat and can cause the system to malfunction. Two different techniques, active cooling and passive cooling, are applied to protect heat generating systems.

The source that provides the power required to operate an LED or LED array is called an LED driver. Constant current power supplies are used to prevent the LEDs from failing by drawing too much current. The constant current LED driver is designed to deliver a constant output current within...

Multimeter (avometer) is used to measure and test different electrical quantities such as voltage, current, resistance. Multimeters are divided into two as analog multimeter and digital multimeter according to the technology they have.

Electromagnetic compatibility (EMC) is the concept of ensuring that electrical equipment and systems operate correctly in an environment, with or in the presence of other electrical devices. EMC limits the electromagnetic energy emitted by devices and ensures that the device continues to operate in the presence of various electromagnetic events.

Electronic devices interact with each other and with the real world through information transfer. Information transfer is done using signals in analog and digital form. Electronic circuits that process any analog signal and provide an analog output are called analog circuits. Electronic circuits that process signals with discrete amplitude, also...

SolidWorks is computer-aided solid modeling software commonly used by designers, draftsmen, mechanical engineers, and construction planners. The cheapest one is the Standard package and approximately $4,000 is required to purchase this package. What is the best free alternative that SolidWorks users can easily get used to?

Multimeter, also known as avometer, is a tester used to measure electrical voltage, current, resistance and so on. Multimeters are mainly of two types, analog and digital. Both are used for measuring and fault detection in electrical circuits.

LEDs are electronic circuit components that convert electrical energy into light with high efficiency. The LED driver is the power source that supplies and regulates power for the safe and convenient operation of LEDs. Constant current and constant voltage drives are both used to power LED light sources.

Energy or particles emitted from a source and moving in the air are called radiation. Radio waves, microwaves, X-rays and gamma rays are types of electromagnetic radiation. Visible light is also a kind of electromagnetic radiation. However, this constitutes only a small part of the electromagnetic spectrum.

T5 and T8 fluorescent tubes are often used for ambient lighting in commercial areas such as offices. T5 fluorescent light bulb is a newer technology than T8. T5 fluorescent light bulb has an efficiency of about 100 lm/W. T8 fluorescent light bulb can reach about 90 lm/W luminous efficacy.
