In this video on current electricity, we explain electric current as the flow of charge and discuss resistance as the opposition to this flow. You'll learn to identify the components of a simple cell and an accumulator, and solve problems involving series and parallel connections of resistors and cells. We also cover the factors affecting the resistance of a uniform wire.
