Insalator
Conductor
Insalator are materials that do not allow electrons to flow easily. Examples of these incude sharpie and water
Conductor are materials that allow electrons to flow through easily. Example of conductors include water and salt and metal
Static electricity occurs when electrons are transferred from one place to another by friction. The object which looses electrons becomes positively charge and the object that gains electrons becomes negatively charge. As opposite charge attract the electrons can be discharge.
Why can static charges be dangerous?
It can cause electrocution. The cloths become charge and you tough a metal object and lightning

In a series circuit the current flows through only one loop. The current is the same at all the points.
In a parallel circuit the current is divided into branches. This means that the current flowing through each component is different.
Current-is how quickly of charges flow through current-symbols I unites - Amps A measured in an ammeter
How to turn a multimeter into an ammeter
To turn a multimeter into an ammeter you need to put one of the wires into com. Then put the other one into Amps . Then you put the powers on. Finally you turn the dial onto A.
How to turn a multimeter into a voltmeter
To turn a multimeter into an voltmeter you need to put one of the wires into com. Next you put one of the wires into volts. After that you turn the power on. Finally you turn the dial to 20V
Voltage is the potential energy per unit charge (electrons) symbol=V units=volt V measure with a voltmeter
As we increase the voltage, the bulb got brighter this is because the electrons stone more energy (have greater charge)
Rules=you must always draw the line with a pencil and a ruler, you must draw the symbols on the line and you must always draw them acuatly
