Electric Charge
Electric charge, a fundamental property of matter, governs the interactions between particles in the universe. This intrinsic characteristic, carried by elementary particles such as electrons and protons, gives rise to the phenomena of attraction and repulsion. With two types – positive and negative – electric charge plays a pivotal role in the workings of electromagnetism. Understanding the principles of electric charge is essential for comprehending diverse fields, from physics and engineering to everyday technologies like electronics. This introduction sets the stage for a nuanced exploration of the nature and implications of electric charge in the fabric of the physical world.
