Current in Potentiometer Solution

Follow our step by step solution on how to calculate Current in Potentiometer?

FIRST Step Consider the formula

I = \frac{x \cdot L}{R}

Next Step Substitute values of Variables

∴

I = \frac{0.021V/mm \cdot 1500mm}{15Ω}

Next Step Convert Units

∴

I = \frac{21V/m \cdot 1.5m}{15Ω}

Next Step Prepare to Evaluate

∴

I = \frac{21 \cdot 1.5}{15}

LAST Step Evaluate

∴

I = 2.1A
