Edited for clarity[edit]

The "all electric radio station" sentence is wonky. There are no steam, gasoline or coal powered radio stations (unless they first turn a generator) which produces electricity. Batteries produce electricity, so saying "all-electric" is wonky. In this case, the batteries were replaced with mains (AC) power. It has to be rectified to be DC power to be useful in a transmitter, and the tube diodes that were created, allowed that. Tube diodes were then replaced with silicon diodes years later. The pentodes, triodes and other thermionic devices (tubes) in the transmitter were historically replaced with silicon devices that transferred current from a high impedance to a low impedance by silicon devices called "transfer resistors", or transistors. Chemistry replaced physics in going from tubes to silicon. — Preceding unsigned comment added by 75.159.230.5 (talk) 19:11, 1 November 2021 (UTC)[reply]
