Question:
StudentAnswer:
(TCO 3) A transformer with a 500 mA AC primary current and a 5:1 turns
ratio has a secondary current of _.
2.5 mA(Incorrect, because it is the product of primary current and turns
ratio but missing the factor of 1,000.)
2.5 A(C

(TCO 1) The unknown value of x in the equation
StudentAnswer:
is _.
3(This is the correct answer. Because the equation is simplified by
reducing coefficients and isolating x on one side of the equation, x is
equal to 3.)
4(This is an incorrect answer. No
