Question 158: Semiconductors and Logic Gates

Question

In the given circuit, the current through zener diode is :

Accepted Answer

Voltage across R
1
is given by $${V_{{R_1}}} = V - {V_Z} = 15 - 10 = 5\,V$$.
Resistance $${R_1} = 500\,\Omega $$
Therefore, current through R
1
is given by
$${I_{{R_1}}} = {{5V} \over {500\,\Omega }} = 0.01\,A$$
Now, current through R
2
is given by
$${I_{{R_2}}} = {{10V} \over {1500\,\Omega }} = 0.067\,A$$
Therefore, the current through Zener diode will be
$$0.1 - 0.0067 = 0.0033\,A = 3.3mA$$
