Δ E 1 = 12400 e V ? 1085 ? = 11.43 e V

Δ E 2 = 12400 304 e V = 40.80 e V

Δ E 1 + Δ E 2 = 54.4 e V 1 n 1 2 - 1 n 2 2 52.23 = 54.4 1 n 1 2 - 1 n 2 2

If n 1 = 1 n 2 = 5

1 20 = ( 1.55 - 1 ) 1 R 1 - 1 R 2

1 f = ( 1.50 - 1 ) 1 R 1 - 1 R 2

Divide (1) by (2), f 20 = 0.55 0.50

f = 22 c m

(I? /2)cos²θ = (18/100)I?
⇒ cos²θ = 9/25
⇒ cosθ = 3/5 ⇒ θ = 53°

    Potential difference across R?
(R? / (R? +R? ) * V is greater than zenor voltage
⇒ i? = V_z/R? = 20/1000 A = 20 mA
Current through R? , i? = (40-V_z)/R? = 20/500 = 40 mA


Current through zener diode = i? - i? = 20 mA
