Capacitive Load Power Consumption Solution

Follow our step by step solution on how to calculate Capacitive Load Power Consumption?

FIRST Step Consider the formula

P L = C L \cdot {V cc}^{2} \cdot f o \cdot S wo

Next Step Substitute values of Variables

∴

P L = 5.01μF \cdot {1.55V}^{2} \cdot 61Hz \cdot 4.01

Next Step Convert Units

∴

P L = 5E-6F \cdot {1.55V}^{2} \cdot 61Hz \cdot 4.01

Next Step Prepare to Evaluate

∴

P L = 5E-6 \cdot {1.55}^{2} \cdot 61 \cdot 4.01

Next Step Evaluate

∴

P L = 0.00294425438025W

Next Step Convert to Output's Unit

∴

P L = 2.94425438025mW

LAST Step Rounding Answer

∴

P L = 2.9443mW
