Which signal outcome results when applying current to a tunnel diode?

A)Negative differential resistance is demonstrated
B)Capacitance increase with increased frequency
C)Increased forward bias current leakage
D)Decreased reverse breakdown voltage threshold

💡 Explanation

Applying current causes electrons to tunnel through the potential barrier via Quantum Tunneling when states exist at the same energy, because increased current leads to decreased voltage. Therefore, negative differential resistance occurs, rather than other effects limited by materials.
