Coulombs to Volts Conversion

Coulomb (C)

A coulomb is the SI unit of electric charge, representing:

  • The charge transported by a one-ampere current in one second
  • Approximately 6.242 ร— 1018 elementary charges
  • The basic unit for measuring electric charge quantity

Volt (V)

A volt is the SI unit of electric potential difference or electromotive force. It represents:

  • The energy per unit charge
  • One joule of energy per coulomb of charge
  • The potential difference that would drive one ampere of current against one ohm resistance

Joule (J)

A joule is the SI unit of energy, work, and heat. It can be understood as:

  • The energy transferred when applying a force of one newton over one meter
  • The energy dissipated when one ampere passes through a one-ohm resistor for one second
  • The work done to produce one watt of power for one second

How to Convert Coulombs to Volts

V = J รท C
V = Voltage (volts)
J = Energy (joules)
C = Charge (coulombs)

Practical Example

Given:

  • Energy = 12 joules
  • Charge = 4 coulombs

Solution:

V = 12 J รท 4 C = 3 V
