Questions & Step-by-Step Solutions
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.
