In an AC circuit, the current lags behind the voltage by 90 degrees in which type of circuit? (2020)

In an AC circuit, the current lags behind the voltage by 90 degrees in which type of circuit? (2020)

Step 1: Understand what AC circuit means. AC stands for Alternating Current, which means the current changes direction periodically.
Step 2: Learn about voltage and current. Voltage is the electrical force that pushes the current through the circuit.
Step 3: Know that in AC circuits, the relationship between voltage and current can vary depending on the type of circuit.
Step 4: Identify the types of circuits: resistive, capacitive, and inductive.
Step 5: Focus on inductive circuits. In these circuits, components like inductors store energy in a magnetic field.
Step 6: Understand the phase difference. In an inductive circuit, the current does not reach its maximum value at the same time as the voltage does.
Step 7: Learn that in an inductive circuit, the current lags behind the voltage by 90 degrees. This means when the voltage is at its peak, the current is at zero.

Inductive Circuits – In inductive circuits, the current lags behind the voltage due to the properties of inductors, which store energy in a magnetic field.
