Discharge duration of single pulse Solution

Follow our step by step solution on how to calculate Discharge duration of single pulse?

FIRST Step Consider the formula

τ s = \frac{V \cdot S ut}{3.25 \cdot {I m}^{\frac{3}{2}}}

Next Step Substitute values of Variables

∴

τ s = \frac{3mm² \cdot 15N/mm²}{3.25 \cdot {0.5A}^{\frac{3}{2}}}

Next Step Convert Units

∴

τ s = \frac{3E-6m² \cdot 1.5E+7Pa}{3.25 \cdot {0.5A}^{\frac{3}{2}}}

Next Step Prepare to Evaluate

∴

τ s = \frac{3E-6 \cdot 1.5E+7}{3.25 \cdot {0.5}^{\frac{3}{2}}}

Next Step Evaluate

∴

τ s = 39.1628371118703s

LAST Step Rounding Answer

∴

τ s = 39.1628s
