Emitter Current of BJT Solution

Follow our step by step solution on how to calculate Emitter Current of BJT?

FIRST Step Consider the formula

I e = I c + I B

Next Step Substitute values of Variables

∴

I e = 5mA + 0.077mA

Next Step Convert Units

∴

I e = 0.005A + 7.7E-5A

Next Step Prepare to Evaluate

∴

I e = 0.005 + 7.7E-5

Next Step Evaluate

∴

I e = 0.005077A

LAST Step Convert to Output's Unit

∴

I e = 5.077mA
