# C=Q/U equivalence for inductor

In order to calculate the time it takes to charge a certain capacitor with value C at a given constant current of a value I to a voltage of value U, I can use: $$C = \frac{Q}{U} = \frac{I\Delta t}{U}$$ Is there something equivalent for an Inductor? like: $$L = \frac{\Phi}{I} = \frac{U\Delta t}{I}$$ I mean, can I calculate the time it takes for a inductor with value L to reach a current I charged with a constant voltage U?

$$C = \frac{I\Delta t}{\Delta U}$$ and $$L = \frac{U\Delta t}{\Delta I}$$
Rewriting gives $$\Delta t = L\frac{\Delta I}{U}$$ which calculates the time it takes to increase the current with $$\ \Delta I \$$ when a fixed voltage U is applied for a given inductance L.
