Which outcome occurs when high energy photons strike a silicon photodiode?

A)Electron-hole pairs increase conductivity
B)Reverse bias voltage collapses quickly
C)Overall device temperature rapidly increases
D)Built-in magnetic fields immediately disappear

💡 Explanation

Electron-hole pairs cause increased conductivity because carriers are generated via the photoelectric effect. Incident photons create electron-hole pairs allowing current to flow through the device, therefore conductivity increases, rather than voltage collapse or magnetic change, which are influenced by different external factors.
