Questions & Step-by-Step Solutions
What is the primary role of capacitors in power systems?
Step 1: Understand what a capacitor is. A capacitor is an electrical component that stores energy in an electric field.
Step 2: Learn about power systems. Power systems are networks that deliver electricity from producers to consumers.
Step 3: Know what reactive power is. Reactive power is the power that helps maintain the voltage levels in the system but does not do any useful work.
Step 4: Recognize the concept of power factor. Power factor is a measure of how effectively electrical power is being used. A higher power factor means more efficient use of electricity.
Step 5: Understand the role of capacitors. Capacitors provide reactive power support, which helps improve the power factor.
Step 6: Realize the benefit. By improving the power factor, capacitors enhance the overall efficiency of the power system.
