Channel Charge Solution

Follow our step by step solution on how to calculate Channel Charge?

FIRST Step Consider the formula

Q ch = C g \cdot (V gc - V t)

Next Step Substitute values of Variables

∴

Q ch = 59.61μF \cdot (7.011V - 0.3V)

Next Step Convert Units

∴

Q ch = 6E-5F \cdot (7.011V - 0.3V)

Next Step Prepare to Evaluate

∴

Q ch = 6E-5 \cdot (7.011 - 0.3)

Next Step Evaluate

∴

Q ch = 0.00040004271C

Next Step Convert to Output's Unit

∴

Q ch = 0.40004271mC

LAST Step Rounding Answer

∴

Q ch = 0.4mC
