Diffusion Current Solution

Follow our step by step solution on how to calculate Diffusion Current?

FIRST Step Consider the formula

I d = 607 \cdot (n) \cdot {(D)}^{\frac{1}{2}} \cdot {(m r)}^{\frac{2}{3}} \cdot {(t)}^{\frac{1}{6}} \cdot (c)

Next Step Substitute values of Variables

∴

I d = 607 \cdot (2) \cdot {(6.9E-6cm²/s)}^{\frac{1}{2}} \cdot {(4mg/s)}^{\frac{2}{3}} \cdot {(4s)}^{\frac{1}{6}} \cdot (3mmol/mm³)

Next Step Convert Units

∴

I d = 607 \cdot (2) \cdot {(6.9E-10m²/s)}^{\frac{1}{2}} \cdot {(4E-6kg/s)}^{\frac{2}{3}} \cdot {(4s)}^{\frac{1}{6}} \cdot (3E+6mol/m³)

Next Step Prepare to Evaluate

∴

I d = 607 \cdot (2) \cdot {(6.9E-10)}^{\frac{1}{2}} \cdot {(4E-6)}^{\frac{2}{3}} \cdot {(4)}^{\frac{1}{6}} \cdot (3E+6)

Next Step Evaluate

∴

I d = 30.372542348209A

Next Step Convert to Output's Unit

∴

I d = 30372542.348209µA

LAST Step Rounding Answer

∴

I d = 3E+7µA
