Convert electrons per second to amps or amps to electrons per second, and estimate total charge and electrons from current over time.

undefined

Current and electron flow are magnitudes. Electron motion is opposite conventional current. Over-time mode assumes constant current.

Electrons Per Second to Amps Formula

The following formula is used to calculate the current in amps based on the number of electrons per second and the elementary charge.

I = e × q

Variables:

  • I is the current in amps
  • e is the number of electrons per second
  • q is the elementary charge magnitude (exactly 1.602176634 × 10⁻¹⁹ coulombs)

To calculate current magnitude, multiply the electron rate by the elementary charge magnitude. Electron motion is opposite conventional current. For constant current over time, charge magnitude is I × t and the transferred electron amount is I × t / q.

What is an Electron?

An electron is a subatomic particle with a negative electric charge. Electrons are found in all atoms and are the primary carrier of electricity in solids. They are extremely small, with a mass approximately 1/1836 that of a proton. Electrons play a crucial role in electricity, magnetism, and thermal conductivity, and they are also involved in chemical bonding and reactions.

How to Calculate Electrons Per Second to Amps?

The following steps outline how to calculate the current in amps from the number of electrons per second.

  1. First, determine the number of electrons per second (e).
  2. Next, use the known value of the elementary charge (q).
  3. Multiply the number of electrons per second by the elementary charge to find the current in amps (I = e * q).
  4. Finally, verify your result using the calculator above.
