Questions & Step-by-Step Solutions
What is the power factor in an AC circuit with a resistive load?
Correct Answer: 1
Step 1: Understand what an AC circuit is. An AC circuit is one that uses alternating current, which changes direction periodically.
Step 2: Know what a resistive load is. A resistive load is a type of electrical load that converts electrical energy into heat, like a light bulb or a heater.
Step 3: Learn about power factor. Power factor is a number that shows how effectively electrical power is being used in a circuit.
Step 4: Recognize that in a purely resistive load, all the power is used effectively. This means there is no wasted power.
Step 5: Conclude that the power factor for a purely resistive load is 1. This means 100% of the power is being used effectively.
