Questions & Step-by-Step Solutions
In an AC circuit, if the current lags the voltage by 30 degrees, what is the type of load?
Step 1: Understand what AC circuit means. AC stands for Alternating Current, where the current and voltage change direction periodically.
Step 2: Know what it means for current to lag behind voltage. If current lags, it means that the current reaches its peak value after the voltage does.
Step 3: Identify the types of loads in an AC circuit. There are mainly three types: resistive, capacitive, and inductive.
Step 4: Recognize that in an inductive load, the current lags the voltage. This is because inductors store energy in a magnetic field and take time to respond to changes in voltage.
Step 5: Conclude that if the current lags the voltage by 30 degrees, the load in the circuit is inductive.
