surface / object

17
Q

Two objects rubbing together produce ________ electricity.

A

static

18
Q

A

at the poles

19
Q

A _______ _______ has only one path, or one circuit, for the electricity to travel.

A

series circuit

20
Q

Who discovered that adding a metal core to a coil of wire increased the magnetism?

A

William Sturgeon

21
Q

What unit measures how much current flows through a given part of a circuit in one second?

A

ampere

22
Q

Who discovered that current traveling through a wire produces a weak magnetic field in the live wire?

A

Hans Christian Oersted

23
Q

Which unit measures the amount of electrical push, or force, in a circuit?

A

volt

24
Q

Who discovered that moving a magnet around or through a loop of wire produces electricity in the wire? (2 people)

A

Joseph Henry & Michael Faraday

25
Q

A coil of wire with a core attached to an electrical source is what?

A

electromagnet

26
Q

The filament in a light bulb is an example of what?

A

resistor

27
Q

What is one way magnets and static electricity are similar?

A

Both can attract and repel objects

28
Q

What is the difference between electrical devices and electronic devices?

A

Electronic devices can communicate information, but electrical devices cannot.

29
Q

Describe one way magnetism produces electricity

A

Moving a magnet around or through a loop of wire produces electricity in the wire. Moving a wire between the north and south poles of two magnets also produces electricity in the wire.

30
Q
