In an AC circuit, when the current increases, inductance opposes this change due to its property of storing energy in a magnetic field. This opposition is described by Lenz's Law, which states that the induced electromotive force (EMF) will act to counter the change in current. As a result, inductance causes a phase shift between the current and voltage, leading to a lagging current in inductive circuits. This behavior can affect the overall impedance and power factor of the circuit.

A pump can be considered a constant horsepower load if it operates at a consistent flow rate and pressure, meaning its power requirement remains stable under those conditions. However, in practice, the power demand of a pump can vary based on factors such as changes in flow rate, fluid viscosity, and system pressure. Therefore, while some pumps may exhibit characteristics of constant horsepower loads within specific operating ranges, they are not universally constant horsepower loads across all conditions.

Resistance measurement in transformers is crucial for assessing the health and performance of the winding and core components.
