Electric charge is a basic property of matter that causes it to experience a force when placed in an electric field. It is a scalar quantity and can be either positive or negative. Electric charges are responsible for many of the phenomena that we experience in our daily lives, including static electricity, electric currents, and electromagnetic forces. It's Discovery: - The discovery of electric charge is usually attributed to the English scientist William Gilbert in the late 16th century. Gilbert conducted various experiments with static electricity and magnetic materials and was the first to use the term "electricus" to describe the phenomenon of charged objects. However, the concept of electric charge can be traced back to the Greek philosopher Thales of Miletus, who observed that rubbing certain materials against each other could cause them to attract or repel each other. Over the centuries, various scientists and inventors have made important contributions to our un
