Questions: VARs is often referred to as quadrature power, or wattless power.

Solution Steps

VARs, or Volt-Ampere Reactive, is a unit used to measure reactive power in an AC electrical system. Reactive power is the component of electrical power that does not perform any work, often referred to as "wattless" power. It is associated with the energy stored in the system's inductors and capacitors.

The term "quadrature power" is used to describe reactive power because it is 90 degrees out of phase with the active power (measured in watts) in an AC circuit. This phase difference is why reactive power does not contribute to the actual work done by the system.

Given the definitions and explanations above, the statement that VARs is often referred to as quadrature power or wattless power is accurate. Both terms describe the nature of reactive power.
