Recombination Lifetime Solution

Follow our step by step solution on how to calculate Recombination Lifetime?

FIRST Step Consider the formula

τ n = {(α r \cdot p 0)}^{- 1}

Next Step Substitute values of Variables

∴

τ n = {(1.2E-6m³/s \cdot 2.3E+111/m³)}^{- 1}

Next Step Prepare to Evaluate

∴

τ n = {(1.2E-6 \cdot 2.3E+11)}^{- 1}

Next Step Evaluate

∴

τ n = 3.6231884057971E-06s

LAST Step Rounding Answer

∴

τ n = 3.6E-6s
