Electric power
P = VI = I²R = V²/R
Where: I = moment of inertia (kg·m²) / current (A), P = power (W) / pressure (Pa), V = volume (m³) / potential difference (V)
Solved example
Given: I = 7, V = 5
Find: P (power (W) / pressure (Pa))
- Formula: P = I·V
- Substitute the values: P = 5·7
- Result: P = 35 W
Answer: P = 35 W
