Questions & Step-by-Step Solutions
In an AC circuit, if the current lags the voltage by 30 degrees, what type of circuit is it?
Step 1: Understand what AC circuit means. AC stands for Alternating Current, which means the current and voltage change direction periodically.
Step 2: Know what it means for current to lag voltage. If current lags voltage, it means that the current reaches its peak value after the voltage does.
Step 3: Remember the phase relationship. In AC circuits, the phase difference between current and voltage can tell us about the type of circuit.
Step 4: Identify the types of circuits. If current leads voltage, it's a capacitive circuit. If current lags voltage, it's an inductive circuit.
Step 5: Conclude that since the current lags the voltage by 30 degrees, this indicates that the circuit is inductive.
