Question: What signal (voltage or otherwise) vs time displays do you have in your house? Answer? I am a little confused as to what exactly this question is asking. My initial suspicions say that a TV because they receive a signal over time and display that as picture on the screen. Also I think that a thermostat would receive a signal of the ambient temperature and display that the temperature and by similar reasoning a oven. And lastly would any device to which the power can be turned on and off with a switch, by the rational that they complete a circuit and it takes time to charge the circuit Any advice on the correct rational for the solutions are greatly appreciated!
