### static electricity

Sentence: A build up of static electricity caused the boy’s hand to be shocked when he reached for the door knob.

Definition: An electrical charge in motion.
• Sentence: In a series circuit, all devices wired into the circuit share the electric current equally.
Definition: a quality of an object which means that electric current cannot flow easily through it.
• Sentence: A coiled wire is inside the light bulb. This wire is made of a material with a high resistance.
Definition: a simple circular path in which an electric current flows only one way through each part of that circuit.
• Sentence: In a series circuit, one missing or burnt-out bulb opens the circuit therefore no bulbs will light.
Definition: a circuit with two or more paths for the electric charge to follow.
• Sentence: A break or missing bulb does not cause all of the lights to go out in a parallel circuit.
Definition: the property of attraction of an object that has a magnetic field. It can attract other objects made of metal
• Sentence: Electricity and magnetism are closely related. Both are the result of charged particles moving.

Definition: the invisible force that loops between the poles of a magnet due to the arrangement of charges. The force is strongest at the poles, or ends, and gets weaker as distance from the magnet.

• Sentence: Iron filings near a horseshoe magnet show that the magnetic field is strongest near the poles.
Definition: a coil of wire that causes a magnetic field when current moves through the wire.
• Sentence: More coils and a larger core makes the electromagnet stronger.
