A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers consist of two coils of wire wrapped around a magnetic core.

• The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.

• The transformer works on the principle of electromagnetic induction, where a changing magnetic field...read more

Data annotation is the process of labeling data to make it usable for machine learning algorithms.

• Data annotation involves adding tags, labels, or notes to data points.

• It helps in training machine learning models by providing labeled data for classification or regression tasks.

• Examples include labeling images with objects or categories, tagging text with sentiment or topics, and annotating audio with speech or music.
