The symbol for electrical current is I. But so is rotational inertia! Are there any other symbols for rotational inertia/electrical current?

I have seen I, J or ##\Theta## as symbols for moment of inertia but you can use any symbol you want if you explain it suffitiently (e.g. with a corresponding comment at the first use).

Much more common is i(t) with the lower case "i". Problem solved?The symbol for electrical current is I.

Really? Huh, this is the first time I've encountered this.Much more common is i(t)

Well, in fairness, it's commonly written both ways, but maybe more often as "I" for DC and more often as "i(t)" for AC and time-varying currents. In any case, you certainly can choose to use either, and since your work involves I=MOI, you can chose to use i(t) for your current in your equations.Really? Huh, this is the first time I've encountered this.
