Electrical and electronic

As summer approaches, with its intense sunshine, many people notice their phones heating up quite quickly, even after only short periods of use. When shooting videos outdoors, taking photos, or using mobile data continuously, if the phone's frame isn't made of aluminum, the heat is noticeably noticeable. Increased phone temperature also causes the battery to drain faster than usual.

In electrical systems, short circuits are one of the most common but also most dangerous faults. If just two wires touch each other or a phase wire touches ground, the current can surge suddenly in a very short time. This will cause the circuit breaker to trip, electrical equipment to stop working, and the wires may even overheat and catch fire.

During electricity usage, there are times when appliances operate less efficiently than usual. Lights may flicker unevenly, pumps may run slowly, or the inverter may display a low voltage error. One of the common causes is voltage drop.

When inspecting the grounding system in electrical cabinets, buildings, or factories, measuring the ground resistance is almost mandatory. If the ground resistance value is not met, the lightning protection and electrical protection system will not function as designed.

When renovating a house, tiling, painting walls, or buying furniture, many people need to know the room's dimensions to calculate the appropriate amount of materials. Measuring with a tape measure is manageable, but it can be quite time-consuming for large rooms or when multiple measurements are required.

Many people looking for a miniature multimeter often wonder if such a small size is sufficient for their needs. In reality, most modern mini multimeters still fully support basic measurements such as AC voltage, DC voltage, resistance, and continuity testing.

## What is a Flow Switch? **_[Flow switches][1]_**, also known as flow control switches, are devices used to detect and monitor the presence or flow rate of

The device incorporates a 6.5-digit multimeter, with a basic DC voltage accuracy of 0.003 percent per year. In full configuration, the system supports up to 120 channels and a scan rate of up to 450 channels per second when using solid-state switching modules.

Since your school days, many of you have undoubtedly heard about and learned about potentiometers. Simply put, it's a type of electrical device with a variable resistance value. This electronic value can be adjusted within a certain range. Thanks to this adjustability, the potentiometer allows for the control of current or applications flowing through a circuit as required.
