SUMMARY
The energy delivered to a 4H inductor with a current described by the equation i = 2t^2 - 1 Amps from time t=1 to t=3 seconds is calculated using the formula dw = Li di. The differential current di is determined as 4t dt, leading to the integral w = L ∫ (2t^2 - 1)(4t) dt from 1 to 3 seconds. The calculations confirm the approach is correct, ensuring accurate energy delivery assessment.
