Contention Current in Ratioed Circuits Solution

Follow our step by step solution on how to calculate Contention Current in Ratioed Circuits?

FIRST Step Consider the formula

i con = (\frac{P st}{V bc}) - (i st + i g + i j)

Next Step Substitute values of Variables

∴

i con = (\frac{67.37mW}{2.02V}) - (1.6mA + 4.5mA + 1.5mA)

Next Step Convert Units

∴

i con = (\frac{0.0674W}{2.02V}) - (0.0016A + 0.0045A + 0.0015A)

Next Step Prepare to Evaluate

∴

i con = (\frac{0.0674}{2.02}) - (0.0016 + 0.0045 + 0.0015)

Next Step Evaluate

∴

i con = 0.0257514851485149A

Next Step Convert to Output's Unit

∴

i con = 25.7514851485149mA

LAST Step Rounding Answer

∴

i con = 25.7515mA
