Master the fundamental concepts of electrical charge and current in this 37-minute GCSE physics revision session designed for students targeting Grade 9 achievement. Explore the principles of electric charge, including positive and negative charges, charge conservation, and the relationship between charge and electrons. Delve into electric current as the flow of charge, understanding how to calculate current using the formula I = Q/t, and examine the factors that affect current flow in electrical circuits. Learn about conventional current versus electron flow, and practice solving problems involving charge, current, and time calculations. Work through exam-style questions and problem-solving techniques specifically tailored to help you achieve the highest GCSE physics grades, with accompanying worksheet materials available for additional practice and reinforcement of key concepts.
