Resistivity

The video tutorial explains the concepts of open and closed circuits using a battery and light bulb. It tests various materials to determine their conductivity, distinguishing between conductors and insulators. The tutorial delves into resistivity and resistance, explaining their relationship and the equation that connects them. It also covers semiconductors and how temperature affects resistivity, highlighting the differences between conductors and semiconductors in terms of temperature dependence.
