If the electric potential at a point in space is known to be zero, then what can be said with
certainty about the electric field at that same point?
An uncharged capacitor is connected in series with a resistor, a dc battery, and an open
switch. At time t = 0 s, the switch is closed. (a) Draw a graph that best describes the
current I through the capacitor as a function of time t. (b) If an inductor is added in series
to this dc circuit and the capacitor is uncharged again with an open switch, then draw a
graph that shows the current I through the capacitor as a function of time starting at t = 0s
when the switch is closed.
