Rossari Biotech Engineer Trainee Interview Questions and Answers

Motor capacity is in Kw because it measures active power while transformer capacity is in kVA because it measures apparent power.

• Motor capacity is measured in Kw because it represents the active power that the motor can produce.

• Transformers are rated in kVA because they are designed to handle both active and reactive power.

• kVA is a measure of apparent power, which is the combination of active power and reactive power.
