Electric Circuit

1
Electric Circuit

• A continuous pathway that can carry an electric
  current The lights in your home are on an
  electric circuit.

2
Electric Current

• A flow of electric charges Electric current
  flows through a circuit.

3
Electric Charge

• A basic property of the tiny particles that make
  up matter it can be positive or negative Some
  particles of matter have electric charge.

4
Static Electricity

• The buildup of electric charges in one place
  Static electricity might make your hair stand
  up.

5
Electric Field

• The area around electric charges in which
  electric forces can act Strong static electric
  charges have large electric fields.

6
Series Circuit

• An electric circuit with only one path that
  current can follow If one bulb in a series
  circuit goes out, the others also go out.

7
Magnetic Poles

• One of the two areas on a magnet where it exerts
  the strongest force Every magnet has two
  magnetic poles.

8
Electromagnet

• A device made up of a current carrying wire coil
  around an iron core You can make an
  electromagnet with a nail, some wire, and a
  battery.

9
Kinetic Energy

• The energy of motion When you move, you have
  kinetic energy.

10
Electric Motor

• A device that converts electricity to motion
  Some toys have electric motors.

11
Generator

• A device that converts other forms of energy into
  electricity People use portable generators when
  the power is out.

12
Insulated

• To protect from electricity by covering with
  rubber or another material that does not carry
  current The red, blue, and green plastic
  insulates these wires.

13
Parallel Circuit

• An electric circuit with two or more paths that
  current can follow If one bulb in a parallel
  circuit goes out, the others stay on

14
Resistance

• The measure of how much a material opposes the
  flow of electric current Most metals have low
  resistance.

15
Magnetic Field

• The space around a magnet in which magnetic
  forces can act The metal filings show where the
  magnetic field is.
