1. Design a circuit, in black box, with the following requirements: a) Input voltage, $$V_{in}$$, (voltage supplied to black box) is between $$0?30\mathrm{V}$$. b) Output voltage, $$V_{\text{out }}$$ should be $$2/5V_{\text{in }}$$. c) Use only $$1/4\mathrm{W}$$ resistors. Design should be safe; i.e. not even a single resistor should burn out or get damaged. Perform power calculations to verify your answer. 2. When do we use VDR and CDR?
