Electrostatic Phenomena
A build-up of electric charge from friction.
What is static electricity?
Stores charge. Two metal plates separated by an insulator
What is a capacitor?
A material that allows electricity to move easily.
What is a conductor?
How do we measure current?
Amperes
A circuit with more than one path
What is a parallel circuit?
Plastic, rubber, or glass. These are examples of? P
What is an insulator?
A device that detects information
What is a sensor?
The circuit is broken and electricity cannot flow.
What is an open circuit?
What particle usually carries current in wires?
Electrons.
Which circuit is more reliable if one device fails: series or parallel?
Parallel
When something gains or loses electrons, it becomes this.
What is charged?
What does a touch screen detect?
Changes in electric fields caused by your finger.
Electricity can flow through the complete path.
What is a closed circuit?
What is the direction of conventional current?
From positive to negative
When there is so much friction in the cloud, the air heats up, causing a spark.
What is lightning?
The insulator between two metal plates.
What is a dielectric?
What does a straight line usually represent in a circuit diagram?
What is a wire?
Providing a path for charge to flow safely into the Earth. (Connecting to earth with a conductor)
What is earthing?
Type of sensor detects light in a camera
What is a CCD/light sensor
