Explanation:
Frost will disturb the smooth flow of air over the wing, unpleasantly
distressing its lifting competence. In other words, this spoils the even flow
of air over the wings, by this means decreasing lifting capability. Also, frost
may avoid the airplane from becoming flying at normal departure speed.
Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .
Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the 3.5 has the units of ohms. Then . . .
Current = (voltage) / (resistance) = (1.5/3.5) = <em>3/7 of an Ampere</em>.
(429 mA, rounded)
