About Abcoulombs
The abcoulomb (abC) equals exactly 10 C - the charge unit of the CGS-EMU (electromagnetic) system, defined as the charge transported by 1 abampere (= 10 A) in 1 s. Two parallel wires each carrying 1 abampere and spaced 1 cm apart experience a force of 2 dyn per centimetre length. The abcoulomb appears in older electromagnetic engineering literature from the early twentieth century. 1 abC = 10 C.
About Coulombs
The coulomb (C) is the SI derived unit of electric charge, equal to the charge transported by a current of 1 A in 1 s. In the 2019 SI revision it is fixed exactly via the elementary charge: 1 C = 1 / (1.602 176 634 × 10⁻¹⁹) e ≈ 6.241 × 10¹⁸ e. Practical benchmarks: a 1 Ah battery stores 3 600 C; a lightning bolt transfers 1-20 C.
