A physical property of particles or objects that causes them to attract or repeal each other without touching.
Define Electric Charge
100
Continues flow of electric charges
What is electric current
100
Closed loop though which current can flow
What is electric circuit?
100
Consist of silicon and an element such as phosphorus that gives the silicon crystal extra electrons.

100
They repel each other
What happens when two charged particles are the same (+,+) (-.-)
200
Is a space around a charged particle where the particle exerts electric force on other particles.
What is an electric field
200
Direct current- current flows in just one direction
Alternating current- current keeps reversing direction

Identify the parts of an electric circuit?
400
Digital- Consist of pulses of voltage, created by repeatedly switching the current off and on
Analog- consists of continuously changing voltage in a circuit.
How to digital and analog signal differ
400
opposition to the flow of electric charges that occurs when electric current travels through matter
What is resistance
500
5 amps
