  1. How Does Electricity Flow?

  2. In order for electricity to flow, it must follow a complete path. The path that electricity can move through is called a circuit (SUR·kit). A circuit is made up of parts that work together to allow electricity to flow.

  3. The electricity that flows through a circuit is called current electricity. Current electricity is moving electrical charge. Current electricity is different from static electricity. Static electricity is a buildup of electrical charge. Static electricity does not flow.

  4. This circuit consists of a source of electrical current, a wire through which the current flows, a switch to control the flow of current, and an object to be lighted. This circuit is closed because there are no gaps in the path.

  5. Current electricity will flow through a closed circuit. In a closed circuit, there are no gaps or breaks in the path. The path is complete. An incomplete path is called an open circuit. No current will flow through an open circuit. There are gaps or breaks in an open circuit.

  6. The current that flows through a circuit can be turned on or off. A device known as a switch (SWICH) controls the current in a circuit. When the switch is in the closed position, the circuit is closed. The path is complete, and current flows. When the switch is in the open position, the circuit is open. The path is incomplete, and no current flows.

  8. André Ampère • How much current is flowing in a circuit can be measured in units called amperes (AM·peerz). The ampere is named after the French physicist André Ampère, who lived from 1775 to 1836.

  9. ammeter • Amperes are measured with an instrument called an ammeter.
