chemistry and physics lesson 12

electrical field

the field around electrically charged objects

electrostatic energy/static electricity

stored energy

capacitor

a gadget that can discharge static electricity when needed.

Current

a stream of electrical energy that flows without stopping

Insulator

protective shield against the flow of electrons.

Electric current

 a flow of electricity through a conductor

Circuit

a circular path that starts and finishes at the same point.

Electrical grid

power plants, power lines, and transformers.It is a network for delivering electricity from producers to consumers.

alternating current/AC

any electricity produced with a motor.

Short circuit

when electricity goes through the shorter path

Battery

a combination of different objects that conduct electricity

Load

what we try to turn on with an electric current

Resistor

anything that slows an electric current

Direct current/dc

when a current flows only in one direction

Volts

energy of an electric charge

Switch

device we use to open and close a circuit. 

Series circuit

 circuit with more than one resistor

watt

the way that we measure how much electricity something produces
