Presentation transcript:

 The unit used to measure the electrical current or flow of electrons through an electrical conductor or circuit.

 A source of electrical energy that is created by a chemical reaction and pushes electric charges within a circuit.

 The connecting points or locations on a battery where the electrical charges leave or enter the battery.

 A path through which electricity flows

 A complete electrical circuit or path through which electricity or current can pass or flow

 Materials through which electrical current can flow. Copper is a good conductor. Most electrical wires are made of copper.

 A flow of electrons; the quantity of electrons that moves through a circuit. Electric current is measured in amps.

 A device that changes or converts mechanical energy into electrical energy.

 A device that converts or changes electrical energy into mechanical energy.

 Materials that do not easily carry or allow the passage or flow of an electric current. Examples are glass, rubber, plastic, and air.

 The unit used to measure the resistance to the flow of electrons or electric current.

 A circuit or electrical path that is broken or incomplete, and so electricity cannot flow through it.

 An electrical circuit in which the electricity can follow more than one path. It is a circuit that connects several objects or resistances in a way that allows each resistance to have its own path. This is the way appliances and lights are connected in homes, so they do not all have to be on at once.

 A measure of how well electricity moves through a material. Insulators have high resistance; conductors have low resistance. Resistance of an object is measured in ohms.

 A circuit in which all the lights or resistors are connected in sequence, or one after the other, forming a single path Through which the electricity can flow. Batteries in a flashlight and small, portable radios are frequently connected in series.

 Electricity that is motionless or at rest; it is produced by rubbing two objects together, such as a resin rod and a piece of silk fabric, or a balloon against a piece of wool fabric.

 A device that allows an electrical circuit to be opened or closed.

 The force or push, given by a battery or generator that moves electrons from one place to another in an electric circuit or conductor.

 The unit used to measure voltage.

 A unit for measuring how quickly or how much an appliance or other device uses electricity.
