The Coulomb (C) in Electric Charge

What is Coulomb (C)

The Coulomb, represented by the symbol 'C', is the standard unit of electric charge in the International System of Units (SI). It quantifies the amount of electric charge carried by a current of one ampere flowing for one second. This means that if you have a current of 1 ampere passing through a conductor for 1 second, the amount of electric charge that flows through that conductor is 1 coulomb.

Mathematically, this can be expressed as:

Where:

• C is the charge in coulombs,
• A is the current in amperes,
• s is the time in seconds.

The coulomb is named after the French physicist Charles-Augustin de Coulomb, who made significant contributions to the study of electricity and magnetism in the 18th century. In practical terms, the Coulomb can be used to describe the amount of charge in batteries, the flow of electricity in circuits, and various phenomena in electrostatics.

Common Conversion Values

When working with electric charge, it is often useful to convert between different units. Below are some common conversion values for coulombs:

• 1 (C) = 1000 (mC)
• 1 (C) = 1000000 (µC)
• 1 (C) = 1000000000 (nC)
• 1 (C) = 0.001 (kC)
• 1 (C) = 0.000001 (MC)
• 1 (C) = 0.1 (abC)
• 1 (C) = 0.2777778 (mAh)
• 1 (C) = 16.66667 (mAmin)
• 1 (C) = 1000 (mAs)
• 1 (C) = 0.0002777778 (Ah)
• 1 (C) = 0.01666667 (Amin)
• 1 (C) = 1 (As)
• 1 (C) = 0.00001036427 (F)

These conversions are helpful when dealing with various applications in physics and electrical engineering. Understanding these can aid in calculations related to electric circuits, battery capacities, and more. With the knowledge of the coulomb, one can effectively measure and manipulate electric charges in different contexts.
