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
  1. 12 Ω
  2. 24 Ω
  3. 36 Ω
  4. 6 Ω

Solution


Pzener=4i=1

⇒i=14 A

i=6R=14

⇒R=24 Ω
