19.2 Series Circuits

A switch is a device that opens and closes the circuit, like a light switch. It is analogous to a valve in a water circuit, as shown on the right side of Figure 19.12. With the switch open, no current passes through the circuit. With the switch closed, it becomes part of the wire, so the current passes through it with no loss of voltage.

$begingroup$ Even better, because the switch cannot throw infinitely fast, there will be finite lengths of time during which one contact is arbitrarily close to the other, so the voltage gradient arbitrarily high. Hence, the spark will begin the very moment that they separate, and will simply be stretched out as they are pulled further apart. Moreover, this same kind of
