## Open an short circuits ## Open and short circuits
A circuit with a break in its loop is called an **open circuit**. When a circuit is open, no current flows. A circuit with a break in its loop is called an **open circuit**. When a circuit is open, no current flows.
A **short circuit** is a path in a circuit that allows current to flow with little or no resistance. This is usually unintentional and results in excessive current flowing through the circuit. A short circuit is the opposite to an open circuit. With an open circuit there is an infinite resistance between the two terminals. A **short circuit** is a path in a circuit that allows current to flow with little or no resistance. This is usually unintentional and results in excessive current flowing through the circuit.

## Vertical circuit diagrams
Sometimes circuits can be represented in a vertical manner rather than in an actual circuit. In this approach current is represented as flowing in a straight line from the voltage source (represented with a circle) to ground.
The circuit below is functionally identical to the previous circuit but represented vertically:
