Ohm's Law, expressed as \( V = I \times R \), is fundamental in understanding how voltage, current, and resistance interact within an electrical circuit. It helps in designing flashlight circuits by ensuring that the components are appropriately matched to prevent issues such as overheating or insufficient power. By applying Ohm's Law, one can calculate the necessary resistance needed to protect the light source and ensure efficient operation. It is crucial for troubleshooting and optimising the circuit for better performance and longevity. Understanding Ohm's Law enables better control and manipulation of electrical parameters within the flashlight.
