How to find the amperage from the formula A = UIt? As well as tension and time?

The work A of an electric current I flowing through a stationary conductor with resistance R is converted into heat and is determined by the formula:
A = U * I * t
Let us express the current strength from this expression:
I = A / (U * t)
Let us express the voltage from the formula for determining the work:
U = A / (I * t)
Let us express the time from the formula for determining the work:
t = A / (U * I)
