Electron Current Density Solution

Follow our step by step solution on how to calculate Electron Current Density?

FIRST Step Consider the formula

J e = J T - J h

Next Step Substitute values of Variables

∴

J e = 0.12A/m² - 0.09A/m²

Next Step Prepare to Evaluate

∴

J e = 0.12 - 0.09

LAST Step Evaluate

∴

J e = 0.03A/m²
