This issue presents a research paper about a new way to measure AC voltage more accurately and quickly. The researchers developed a special device that can measure the strength of alternating current (AC) electricity very fast. This device uses a method called “iterative additive error correction” to fix any small mistakes in its measurements. This makes the readings very accurate. The new method is faster and more precise than older ways of measuring AC voltage. This improvement could be useful in many areas where we need to measure electricity, like in power plants, factories, or even in home appliances.
