VE Commercial Vehicles Electrical Maintenance Technician Interview Questions and Answers

An ideal transformer is a theoretical transformer with no losses and perfect efficiency.

• An ideal transformer has no resistance, leakage inductance, or core losses.

• It has a turns ratio that perfectly converts voltage and current from primary to secondary windings.

• Efficiency is 100% in an ideal transformer.

• Real transformers have losses due to resistance, eddy currents, and hysteresis.

kVA is the apparent power, while kW is the real power. The relationship between them is determined by the power factor.

• kVA is the product of voltage and current in a circuit, while kW is the actual power consumed by the load.

• The relationship between kVA and kW is determined by the power factor of the load.

• Power factor = kW / kVA. A power factor of 1 indicates all power is being used efficiently.

• For example, if a load h...read more
