(B) The current through the load resistor $R_L$ is given by:$i = \frac{V_z}{R_L} = \frac{10 \, V}{5 \, k\Omega} = 2 \, mA$The total current $I$ flowing through the series resistor is:$I = \frac{V_{in} - V_z}{R_s} = \frac{24 \, V - 10 \, V}{1 \, k\Omega} = \frac{14 \, V}{1 \, k\Omega} = 14 \, mA$The current through the zener diode $I_z$ is:$I_z = I - i = 14 \, mA - 2 \, mA = 12 \, mA$The power dissipated across the zener diode is:$P = I_z 	imes V_z = 12 \, mA 	imes 10 \, V = 120 \, mW$

For the given circuit,the power across the zener diode is ..... $mW$.
