Total Base Current Solution

Follow our step by step solution on how to calculate Total Base Current?

FIRST Step Consider the formula

I B = I B1 + I B2

Next Step Substitute values of Variables

∴

I B = 4.22mA + 3.45mA

Next Step Convert Units

∴

I B = 0.0042A + 0.0035A

Next Step Prepare to Evaluate

∴

I B = 0.0042 + 0.0035

Next Step Evaluate

∴

I B = 0.00767A

LAST Step Convert to Output's Unit

∴

I B = 7.67mA
