Which consequence results when electrons experience quantum tunneling in a Josephson junction?

A)Supercurrent is established across barrier
B)Resistance increases dramatically
C)Thermal runaway destroys the crystal
D)Photons are emitted chaotically

💡 Explanation

Supercurrent emerges because Cooper pairs pass through the insulating barrier via quantum tunneling, a mechanism permitted by quantum mechanics; therefore, a current flows rather than resistance spiking, because the electrons act collectively.
