: in an exponential expression such as A=be -(t/RC) power, we cannot attach units to the exponent -(t/RC) beacause a base, such as e can only be raised to a pure number. consequently, if the variable t in this equation is measured in seconds, what does this imply about the units on the product RC?

in an exponential expression such as A=b*e^-(t/RC) power, we cannot attach units to the exponent -(t/RC) because a base, such as e, can only be raised to a pure number. consequently, if the variable t in this equation is measured in seconds, what does this imply about the units on the product RC?
---------------------------
RC must also be in seconds so the units cancel leaving t/RC a pure number.
