GCSE Physics - V = IR Equation & Current/Potential Difference Graphs #15

The video tutorial explains Ohm's Law (V=IR), its importance in electricity, and how to calculate voltage and resistance in circuits. It discusses the relationship between voltage, current, and resistance, emphasizing that as voltage increases, current increases proportionally if resistance remains constant. The tutorial also covers graphing current versus potential difference, the effects of temperature on resistance, and the behavior of filament lamps and diodes in circuits.
