Determine the current through zener diode for the circuit shown in figure is: (Given: zener diode break down voltage $$V_z=5.6V$$)

Correct option is C. $$10mA$$For zener brak down potential difference across $$800\Omega $$ resistor will be $$5.6V$$4$$V_z=5.6V$$$$i_2=\dfrac{V_z}{800}=\dfrac{5.6}{800}=7mA$$$$\Delta V$$ across $$200\Omega =9-5.6=3.4V$$$$i_1=\dfrac{3.4}{200}=17mA$$$$i_1=1_2+i_z$$$$i_z=17mA-7mA=10mA$$

Correct option is C. $$10mA$$
For zener brak down potential difference across $$800\Omega $$ resistor will be $$5.6V$$4
$$V_z=5.6V$$
$$i_2=\dfrac{V_z}{800}=\dfrac{5.6}{800}=7mA$$
$$\Delta V$$ across $$200\Omega =9-5.6=3.4V$$
$$i_1=\dfrac{3.4}{200}=17mA$$
$$i_1=1_2+i_z$$
$$i_z=17mA-7mA=10mA$$
