PHYSICS - Electricity - Resistors

The video tutorial explains the concept of electrical resistance and resistors, starting with the basics of electric current and conductors. It introduces Ohm's Law, which describes the relationship between voltage, current, and resistance. The tutorial provides practical examples to calculate resistance and voltage in circuits. It also discusses how temperature affects resistance, particularly in conductors and filament bulbs.

How can you calculate the resistance of a wire given the current and voltage?

Describe the relationship between temperature and resistance in conductors.
