Transcription: In this lesson we will be discussing charge, current and electromotive force. Let's begin our discussion with charge. Charge is an excess or deficiency of electrons in a body. Charge may be either positive or negative. Unlike charges attract, like charges repel. According to Faraday's first law derived through experiments with a silver nitrate solution, the mass of silver which leaves the anode and deposits on the cathode is directly proportional to the quantity of charge passing through the electrode. The SI unit of charge is the coulomb and represents the electrical charge carried by 6.24 x ...
