U+23DA. The one ground character Unicode has, named for the earth ground of a circuit. No key, no Alt code and no HTML name: it is entered by code point or copied. Added in Unicode 4.1 (2005).
U+2393. The direct current sign printed on devices that need or supply DC. Unicode calls it form two; form one is a plain long dash, further down. No Alt code.
U+23E6. Unicode's sign for alternating current, the kind that keeps reversing direction. unicode-math names it \accurrent.
U+223F. One cycle of a sine wave, the usual waveform of mains power. Unicode gives it alternating current as a second name. ∿ in HTML.
Made of V and U+2393: the letter for volts set before the direct current sign.
U+23DB. The fuse sign of a circuit diagram, which joined Unicode together with ⏚.
U+26A1. A jagged flash, the only sign in this table that says danger. Unicode's other names for it are thunder and lightning symbol.
Two capitals, the common abbreviation of direct: current that flows in one direction only.
Two capitals for alternating, often written before the word current or voltage.
U+23E4. A long level stroke with two names in Unicode: straightness, a tolerance mark of technical drawings, and direct current symbol form one.
U+23E7. Named electrical intersection. ⏧ in HTML.
U+2126. The unit of resistance as a character of its own. Unicode prefers the Greek capital omega, U+03A9, for the same job. \textohm in LaTeX text.
U+2127. Conductance once had this sign, read mho, before the siemens took over; the glyph is Ω stood on its head. Its entity is ℧, and \mho in LaTeX needs the amssymb package.
U+1F50C. A mains plug, one of the few emoji about electricity. No emoji shows a resistor, a diode or a ground sign.
U+1F50B. A battery cell, the emoji for a source of direct current.
U+1CC09. A piece of a resistor for circuits drawn out of characters. It arrived in Unicode 16.0 (2024) with a set made for old computer screens, and most devices still show an empty box.
U+1CC0F. A diode pointing right, from the same set; its partner points left. No LED and no other diode types have characters.
U+1CC13. A capacitor lying flat, the third component of that set shown here.
The ground symbol is ⏚, Earth ground, U+23DA. The DC symbol is ⎓, Direct current symbol form two, and the AC symbol is ⏦, AC current. None has a key or an Alt code, so they are here to copy.

Ground, DC and AC
⏚ is the character for earth ground. ⎓ is the direct current symbol found on many electronic devices that need or produce DC. For AC current Unicode has two: ⏦, and the sine wave ∿, which it also names alternating current.
How to type the ground symbol
No keyboard has ⏚, ⎓ or ⏦, and no ground symbol alt code exists. They are entered by code point: U+23DA, U+2393 and U+23E6. Of the ground and current signs, only the sine wave has an HTML name, ∿.
Volts DC is written V⎓: the letter V, then the direct current symbol.
⏛ is the fuse sign, added to Unicode in the same version as ⏚.
Questions and answers
What are the DC and AC current symbols?
The DC current symbol is ⎓, U+2393. The AC current symbol is ⏦, U+23E6, and the sine wave ∿ is a second symbol for alternating current. In letters they are simply DC and AC.
Is there a DC symbol alt code?
No. Neither table behind Alt codes holds a ground or current sign, so there is no alt code for direct current, for ground or for AC. On a keyboard the DC symbol and the AC symbol are entered by their code points.
Is there a resistor emoji?
No emoji shows a resistor. Unicode 16.0 added resistor, diode and capacitor pieces as plain characters, and few fonts draw them yet, so a resistor symbol to copy and paste may arrive as an empty box.
Is there a diode alt code?
No. Alt codes reach two old character tables, and neither holds a diode, an LED or a resistor. Unicode has two types of diode symbol, left-pointing and right-pointing, both added in version 16.0.
Is there an isolated ground symbol?
Not as a character. Unicode has one ground sign, ⏚, named Earth ground, and no character is named isolated ground.
