Junction Voltage Solution

Follow our step by step solution on how to calculate Junction Voltage?

FIRST Step Consider the formula

V j = V - (R se(p) + R se(n)) \cdot I

Next Step Substitute values of Variables

∴

V j = 120V - (23.3Ω + 476.7Ω) \cdot 0.2mA

Next Step Convert Units

∴

V j = 120V - (23.3Ω + 476.7Ω) \cdot 0.0002A

Next Step Prepare to Evaluate

∴

V j = 120 - (23.3 + 476.7) \cdot 0.0002

LAST Step Evaluate

∴

V j = 119.9V
