Question

A Zener diode with a breakdown voltage of 4 V is connected in series with a resistance R to a battery of emf 10 V . The maximum power dissipation rating for the Zener diode is 1 W . The value of R to ensure maximum power dissipation across the diode is, 12 Ω, 24 Ω, 36 Ω, 6 Ω

MARKS App · Accepted Answer

P zener = 4 i = 1 ⇒ i = 1 4 A i = 6 R = 1 4 ⇒ R = 24 Ω
