← ScienceWhich risk increases when a signal generator's frequency nears transmission line resonance?
A)Standing waves cause voltage peaks✓
B)Harmonic distortion exceeds acceptable limits
C)Skin effect diminishes signal clarity
D)Dielectric breakdown lowers impedance levels
💡 Explanation
Standing wave formation causes voltage peaks because the incident and reflected waves constructively interfere at specific locations, therefore increasing insulator failure risk rather than simple harmonic increases because the generator circuit is already tuned near its operational limits.
