Chapitre 98: A Rather Technical Meeting

The engineers of the Axelsen & Nielsen Companies were gathered in the drawing room, intently watching a demonstration being conducted by Poul.

Poul had set up two sets of primary and secondary wires, each connected to voltmeters, with one set powered by a direct current source and the other by an alternating current source. The engineers were examining the apparatus closely, trying to spot any differences between the two.

It was Walter who noticed something unique about the readings on the voltmeters. He raised his hand and spoke up.

"I believe the voltmeter reading that is connected to the alternate current source moves left and right, while the voltmeter connected to the direct current source only moves once, when the switch is first turned on, and then stays at zero," Walter observed.

Poul nodded, impressed by Walter's sharp observation. "Excellent, Mr. Schneider. Can you explain why that is?"
