ELECTRICITY
This is an object with equal numbers of positive and negative charges.
An object that has gained or lost electrons is called this.
charged
An object connected to Earth to remove excess charge is called this.
earthed (grounded)
A charged object with more electrons than protons has this type of charge
negative charge
This material does not allow charges to move freely and is often used to cover electrical wires.
insulator
This is the flow of electric charge through a circuit.
Current
Rubber, plastic, and glass are examples of this type of material.
insulator
In this type of circuit, components are connected one after another in a single path.
series circuit
A dielectric's (insulator) main purpose is to do this inside a capacitor.
Prevent current from flowing between the two metal plates.
Small squares that an image is made of
pixels
This unit measures electric current
Amperes
This is the push that moves charges through a circuit.
voltage
In this type of circuit, components have separate paths for current.
parallel circuit
This is the energy source for an electric circuit
battery/cell
The grid that absorbs light to make an image
CCD
Materials like copper and aluminum are good examples of this.
Conductor
A complete path for electricity to flow is called this.
circuit
This component stores electrical charge and energy. (two metal plates that are separated by an insulator)
capacitor
In this type of circuit all of the components are in a single loop
series circuit
Parallel circuit
This unit measures electrical power.
Watts
How much a material opposes or slows the flow of electric current.
Resistance
A dielectric is commonly found inside this electrical component.
capacitor
This enables you to turn a component on or off
switch
The current in a wire is
the charge flowing per second
