Question 195Electricity/Electronics - Assistant Engineer70% to pass
In terms of load type, in what type of alternating current circuit will the voltage always lead the current?
AI Explanation
The correct answer is D) inductive circuit.
In an inductive circuit, the voltage will always lead the current. This is because the inductor opposes changes in the current, causing the current to lag behind the voltage. The voltage leads the current by 90 degrees in a purely inductive circuit.
The other options are incorrect because: A) in a capacitive circuit, the current leads the voltage; B) in a resistive circuit, the voltage and current are in phase; and C) in a resistive-capacitive circuit, the relationship between voltage and current depends on the relative values of the resistance and capacitance.
