How do I measure resistance?
February 14, 2025 341
Wondering about resistance measurement methods! In this article, we will cover basic resistance measurements and precautions. Resistance is very important in electronic device circuits. If the resistance is not appropriate, it can lead to malfunctions and other problems. However, electricity is not visible. To find out if the resistance in a circuit is appropriate, you need to use a specialized measuring instrument. To measure resistance, you need to use a measuring instrument...

What is the difference between a signal analyzer and a spectrum analyzer?
February 14, 2025 589
Spectrum analyzers are primarily used to measure the amplitude of an input signal in relation to its frequency. A signal analyzer, on the other hand, measures both the amplitude and phase of an input signal at a single frequency. For more information, see the technical overview Spectrum Analyzers and Signal Analyzers. ,

What is alternating current (AC)?
February 14, 2025 342
Alternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...
