Physics · Alternating Current
In an R-L series circuit, if the higher-order harmonics in the supply voltage increase significantly while keeping the fundamental component constant, the overall RMS current in the circuit will:
- 1become completely in phase with the supply voltage
- 2decrease due to increased inductive reactance at higher frequencies✓
- 3increase significantly
- 4remain exactly the same
Correct answer
decrease due to increased inductive reactance at higher frequencies
