218 Chapt. 28 Circuits Say we have just connected the circuit with the capacitor initially uncharged. What is the formula for time-zero (i.e., initial) current in terms quantities appearing in the formula just given? At time inFnity, what is the formula for capacitor charge in terms quantities appearing in the formula just given? 028 qfull 00840 3 5 0 tough thinking: non-ohmic devices 14. Consider a generic device where current I through in the direction of the potential drop V across the device is a strictly increasing function of the potential drop V . ±or V = 0, I = 0. We assume the device operates symmetrically whichever way the potential drop is placed across it. a) The I-V curve (current-versus-voltage curve AKA current-voltage or I-V characteristic) for a device is a plot of current through versus voltage drop across. Since our generic device behaves symmetrically, is the I-V curve an even or odd function of V ? b) Sketch the
