Electric Basics
The attraction and repulsion between charged objects.
Electric Force
In order to create static electricity, this charge is transferred.
Electron
The loss of static electricity,when one object transfer to another object.
Static Charge
As the resistance increases it will cause the electric current to do this (if voltage stays the same).
Decrease
Copper, silver, and aluminum are examples of this.
Conductor
The area surrounding a charged object.
Electric Field
The build up of charges on an object, but do not flow continuously.
Static Electricity
An electrical device that is connected so that it makes a path for electric charges to move.
Electric Circuit
As the voltage increases it will cause the electric current to do this (if resistance stays the same).
Increase
Which diagram shows attraction?
Diagram 2
Wood, rubber, plastic, and glass are examples of this.
Insulator
Rubbing of 2 neutral objects together. Electrons leave one and go to the other.
Friction
Material or device that transfers electricity.
Conductor
The difficulty of passing an electric current through a substance.
Resistance
In this diagram (picture 1) what can you do to increase the current in this circuit?
INCREASE the number of batteries or VOLTAGE and DECREASE the RESISTANCE by removing light bulbs.
For an object to become positively charged this happens to the electrons.
When a charged object touches another object electrons can transfer to the other object.
Conduction
A substance or device which does not readily conduct electricity.
Insulator
The flow of electric charges.
Electric Current
When a charged balloon comes close to the wall the balloon will do this to the electrons in the wall, and make the wall this charge.
Repel, Positive
For an object to become negatively charged, this happens to electrons.
Gains
When a charged object is brought near another object, the charges separate in the other object or repel each other (electrons move to one side of the object).
Induction
The potential energy of a charged object because of where it is in an electric field
Voltage
The 4 ways to increase resistance in a wire:
1. Resistance
2. Length
3. Temperature
4. Diameter
The sleeve will LOSE electrons and become this charge, and the balloon will GAIN electrons and become this charge.
Positive, Negative
