A constant voltage of 12.00 V has been observed over a certain time interval across a 2.60 H inductor. The current through the inductor, measured as 3.00 A at the beginning of the time interval, was observed to increase at a constant rate to a value of 7.00 A at the end of the time interval. How long was this time interval?
Given v12.00V, L2.60H, Δi4.00A The voltage across an inductor is given by: v L*di/dt v L*Δi/Δt Δt (L/v)Δi 0.87s
