The kanji 電 (den) fundamentally represents "electricity," "lightning," or anything related to electrical phenomena. This includes the concepts of electrical current, electrical devices, and things powered by electricity. It evokes a sense of suddenness, power, and the unseen force that drives modern technology.

The kanji 電 is a phono-semantic compound (形声文字, けいせいもじ). The left side is 雨 (ame, "rain") indicating association with weather phenomena. The right side is 申 (mōsu, "to say, to report"), which also serves a phonetic role (den). It suggests the idea of "lightning" which is like "rain" but conveys a message from the sky. Over time, it broadened to include the more general concept of "electricity."
