Enter the current and the time into the calculator to determine the charge flow. This calculator helps in understanding the total charge transferred over a period of time in an electrical circuit.

Charge Flow Formula

The following formula is used to calculate the charge flow.

Q = I * t

Variables:

  • Q is the charge flow (coulombs)
  • I is the current (amperes)
  • t is the time (seconds)

To calculate the charge flow, multiply the current by the time.

What is Charge Flow?

Charge flow, often measured in coulombs, is the quantity of electricity that is transferred by an electric current in a given time. It is a fundamental concept in the field of electrical engineering and physics, representing the movement of electric charge carriers, such as electrons, through a conductor. The charge flow is directly proportional to the current and the time for which the current flows.

How to Calculate Charge Flow?

The following steps outline how to calculate the Charge Flow.


  1. First, determine the current (I) in the circuit in amperes.
  2. Next, determine the time (t) in seconds during which the current flows.
  3. Next, gather the formula from above = Q = I * t.
  4. Finally, calculate the Charge Flow (Q) in coulombs.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
