The International System of Units (SI) functions as the global standard for measurement. It encompasses a unified set of units that are derived on fundamental physical quantities. These base units, such as the meter for length and the kilogram for mass, serve as the foundation for deriving other units within the system. The SI system adopts a decim

Relays are electromechanical instruments that utilize an electromagnet to switch an electrical circuit. The basic arrangement of a relay comprises a coil, armature, contacts, and a spring mechanism. When current flows through the coil, it creates a magnetic field which draws the armature, causing the contacts to close. This event allows for the con
