The Basics of Electricity: Understanding Voltage, Resistance, and Current

The video tutorial explains the basics of electricity, focusing on the flow of electrons and the concept of conventional current. It discusses the properties of conductors and insulators, highlighting the role of atomic structure in conductivity. The tutorial also covers the three main units used in circuits: voltage, current, and resistance, using water analogies to simplify these concepts. Voltage is likened to water pressure, current to the flow of water, and resistance to obstacles in the flow. The video emphasizes the importance of understanding these concepts for practical applications in engineering and safety.

Describe how the outermost electrons affect a material's conductivity.

What happens to current when resistance increases in a circuit?
