Demonstrating high-voltage generation and wireless power transfer concepts can be complex due to the need for clear circuit design, component selection, and safe testing methods. Beginners often find it difficult to understand how resonance and electromagnetic induction work in practical high-frequency systems.
This article presents the design and construction of a mini Tesla coil that operates on the principles of electromagnetic induction and LC resonance. Using simple, easily available components, the project explains the circuit, PCB layout, assembly process, and testing method to achieve wireless lighting of bulbs without physical connections.
