What Are Coulombs and Millicoulombs?
Coulomb (C) Definition
The Coulomb (C) is the SI unit of electric charge. It is defined as the charge transported by a constant current of one ampere (A) in one second (s):
Named after French physicist Charles-Augustin de Coulomb, this unit is used for large-scale electrical calculations in physics and engineering.
Millicoulomb (mC) Definition
The Millicoulomb (mC) is a subunit of the Coulomb commonly used for smaller charge measurements. It is equal to one-thousandth of a Coulomb:
This unit is frequently used in electronics, laboratory experiments, and applications where smaller charge quantities are measured.

Understanding Electric Charge in Context
The Fundamental Nature of Electric Charge
Electric charge is a fundamental property of subatomic particles that determines their electromagnetic interactions. Key characteristics include:
- Quantization: Charge exists in discrete units (multiples of the elementary charge e = 1.602 × 10⁻¹⁹ C)
- Conservation: The total electric charge in an isolated system remains constant
- Two Types: Positive and negative charges, with like charges repelling and opposite charges attracting
Relationship to Other Electrical Units
Understanding Coulombs helps connect various electrical concepts:
- Current (Amperes): 1 Ampere = 1 Coulomb per second
- Voltage (Volts): 1 Volt = 1 Joule per Coulomb
- Capacitance (Farads): 1 Farad = 1 Coulomb per Volt
Common Mistake to Avoid
Don't confuse electric charge (Coulombs) with electrical energy (Joules). While related through voltage (Joules = Coulombs × Volts), they represent different physical quantities.
Historical Context and Modern Usage
Charles-Augustin de Coulomb
The Coulomb unit is named after French physicist Charles-Augustin de Coulomb (1736-1806), who formulated Coulomb's Law describing the electrostatic force between charged particles. His work laid the foundation for the quantitative study of electromagnetism.
