The line current supplying a squirrel-cage motor can be computed using the formula: I(LINE) = VA / (E(LINE) x ____)
A) 1.543
B) 1.732
C) 2.4
D) 5

Question

Quizplus · Accepted Answer

The missing factor in the formula is the square root of three (1.732), which is the ratio of the phase voltage to the line voltage in a three-phase system. Therefore, the correct formula is I(LINE) = VA / (E(LINE) x 1.732).
