Joule heating
H = I²Rt
Where: H = maximum height (m) / heat (J), I = moment of inertia (kg·m²) / current (A), R = range / radius / resistance, t = time (s)
Solved example
Given: I = 7, R = 5, t = 10
Find: H (maximum height (m) / heat (J))
- Formula: H = I²·R·t
- Substitute the values: H = 10·5·7²
- Result: H = 2450 J
Answer: H = 2450 J
