Drain Current of Class B Amplifier Solution

Follow our step by step solution on how to calculate Drain Current of Class B Amplifier?

FIRST Step Consider the formula

I d = 2 \cdot (\frac{I out}{π})

Next Step Substitute values of Variables

∴

I d = 2 \cdot (\frac{0.023mA}{π})

Next Step Substitute values of Constants

∴

I d = 2 \cdot (\frac{0.023mA}{3.1416})

Next Step Convert Units

∴

I d = 2 \cdot (\frac{2.3E-5A}{3.1416})

Next Step Prepare to Evaluate

∴

I d = 2 \cdot (\frac{2.3E-5}{3.1416})

Next Step Evaluate

∴

I d = 1.46422547644544E-05A

Next Step Convert to Output's Unit

∴

I d = 0.0146422547644544mA

LAST Step Rounding Answer

∴

I d = 0.0146mA
