The Kirchhoff's second law tells that the sum of voltage differences around the circuit loop is zero, in complete analogy. In this figure we clearly see current loops. It is useful to keep in mind that currents flow very much like water. Ohm's law and the behaviour of various resistors can be understood by the analogy of resistors and thin and thick tubes. Large resistors behave like very thin and long tubes, or pinched tubes which do not allow large currents of water.
Small resistors behave like very wide tubes, where large water currents can flow easily.
Although the water model is useful, it is important to realize its limitations. A break in an electric circuit causes the electricity to stop flowing, it does not spill out of the end of wire like water would from a broken pipe. An electric circuit is NOT analogous to a sprinkler system used to water lawns. Similarly to a valve which blocks a flow of water, a switch puts a gap in the conducting path to stop the flow of electricity.
