Defining Resistance, Ohmic vs. Non-Ohmic and Electric Power

The video tutorial covers the definition of resistance, the difference between ohmic and non-ohmic substances, and the graphical representation of electric potential energy in circuits. It explains Ohm's Law, the role of a battery in a circuit, and how electric potential energy is converted to heat, light, and sound. The tutorial also introduces the concept of electric power, providing equations to calculate it using current, resistance, and electric potential difference.
