Introduction to Electrical Charge and Current: Definition and Calculation

The video tutorial explains electric current as the flow of electric charge in a circuit, measured by the amount of charge passing a point per second. It discusses factors affecting current size, such as charge density, and emphasizes the conservation of current in circuits. The tutorial introduces the equation Q = I * T for calculating current, charge, or time, and provides examples to illustrate its application. The video concludes with a summary of key points on electrical charge and current.
