Calculation path

Estimate time required to deposit or produce a target mass at constant current. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

t=mzF/(I M eta)

What you provide

What you provide

  • Target deposited mass expressed in g, using the same scenario as the other inputs
  • Electrons per deposited atom or ion, using the same scenario as the other inputs
  • Electric current expressed in A, using the same scenario as the other inputs
  • Deposited species molar mass expressed in g/mol, using the same scenario as the other inputs
  • Current efficiency, using the same scenario as the other inputs

What you receive

What you receive

  • Required time in s from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Current is constant, electron stoichiometry is correct, and efficiency captures all parasitic current loss.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
