Instantaneous Circulating Current Solution

Follow our step by step solution on how to calculate Instantaneous Circulating Current?

FIRST Step Consider the formula

i r(dual) = \frac{2 \cdot V in(dual) \cdot (\cos (ω (dual) \cdot t (dual)) - \cos (α 1(dual)))}{ω (dual) \cdot L r(dual)}

Next Step Substitute values of Variables

∴

i r(dual) = \frac{2 \cdot 125V \cdot (\cos (100rad/s \cdot 30s) - \cos (22°))}{100rad/s \cdot 2.3H}

Next Step Convert Units

∴

i r(dual) = \frac{2 \cdot 125V \cdot (\cos (100rad/s \cdot 30s) - \cos (0.384rad))}{100rad/s \cdot 2.3H}

Next Step Prepare to Evaluate

∴

i r(dual) = \frac{2 \cdot 125 \cdot (\cos (100 \cdot 30) - \cos (0.384))}{100 \cdot 2.3}

Next Step Evaluate

∴

i r(dual) = -2.06833266788322A

LAST Step Rounding Answer

∴

i r(dual) = -2.0683A
