(10 Marks) iii. An LVDT has a secondary voltage of 5 V for a displacement of 112.5 mm. Determine the output voltage for a core displacement of 8.0 mm from its central position. iv. Photoconductive cells are used to control relays. The cells' resistance in 100 (5 Marks) illuminated and 1 kwhen they are in the dark. When the cell is illuminated, the relay in Q when supplied with 10 mA from a 30-V supply, and it must be de-energized when the cell is in the dark. The circuit is as shown in Fig. 4, where R is a current-limiting resistor and calculate the series resistance and dark current. (Neglect relay inductance)
