← ScienceWhich outcome occurs when a PCB trace's length increases?
A)Increased propagation delay and impedance✓
B)Reduced parasitic inductance and capacitance
C)Decreased EMI susceptibility and crosstalk
D)Enhanced thermal dissipation and stability
💡 Explanation
Increased trace length enhances the *stray capacitance*, causing increased signal propagation delay because the time to charge the capacitor goes up; therefore impedance rises rather than inductance falling, without directly affecting EMI or thermal properties.
