I believe the answer to #3 is misleading.
Question 3: Power factor correction is accomplished by calculating the value of the _________ that needs to be connected to the circuit.
Resistance
Inductance
Capacitance
Impedance
The correction could be either Inductive or Capacitive depending on the load to be corrected. Usually, you want to correct an inductive load – but not always. Recommend the correct answer to be Inductance.
Question 3 is misleading. In many cases, power factor correction would be need to be capacitive, however this is only in lagging power factors. In leading power factors, the correction would be inductive. Without any mention of if the power factor is leading or lagging, you cannot be certain.
