👉 The term "flashpan" is a technical term in electrical engineering that refers to a type of high-voltage, low-current circuit or switch. It was invented by Walter H. Schmitt in 1947 and is now commonly used for describing a circuit with a very small resistance or capacitance. Flashpans are usually used in the design of power supplies or transformers because they can be used to reduce the resistance and improve the performance of the circuit.
