Questions & Step-by-Step Solutions
In an AC circuit, the current lags the voltage by 90 degrees in which of the following components? (2020)
Step 1: Understand what AC circuit means. AC stands for Alternating Current, where the current and voltage change direction periodically.
Step 2: Learn about components in an AC circuit. Common components include resistors, capacitors, and inductors.
Step 3: Know the behavior of current and voltage in these components. In a resistor, current and voltage are in phase (0 degrees). In a capacitor, current leads voltage by 90 degrees.
Step 4: Focus on inductors. In an inductor, the current lags behind the voltage by 90 degrees.
Step 5: Conclude that the answer to the question is the inductor, as it is the component where current lags voltage by 90 degrees.
