QUESTION FIVE A. For the circuit in Figure 6: i. Determine the output voltage at the Zener knee current and maximum Zener current. [4 marks] ii. Calculate the value of the series resistor that should be used. [2 marks] iii. Determine the minimum value of the load resistor that can be used. [4 marks] Assume that the Zener voltage is 15 V at a Zener test current of 17 mA. The Zener knee current is 0.25 mA, Zener impedance is 14 Ohms and the maximum power dissipation of the Zener diode is 1,000 mW. R VOUT + +o VIN 24 V 1N4744A RL Figure 6

Object Real image 1. Draw and explain the two types of lenses. 2. In our lab, we will focus on converging lenses. The thin lens equation is given as \frac{1}{d_o} + \frac{1}{d_i} = \frac{1}{f} where $d_o$ is the object distance, $d_i$ is the image distance, and $f$ is the focal length of the lens (see diagram). If you write $d_i$ as a function of the total length $L$, the equation becomes $\frac{1}{d_o} + \frac{1}{L - d_o} = \frac{1}{f}$ Show that this equation is quadratic in $d_o$ (be careful of your algebra!) PHY 1054L L6: Focal length of a Thin Lens 2022-07-09 3. The end result of the previous question gives $d_o^2 - Ld_o + fL = 0$. Using this and a focal length of $f = 0.100$ m, and a length of $L = 0.900$ m, solve for $d_o$. What do you think these two solutions mean for the image? What happens if $L = 10.0$ m?
