16
Q

What is electricity

A

It is the flow of electrons from atom to atom in a conductive material

17
Q

A

4 or more

18
Q

How many electrons are on the outer shell of a conductor

A

3 or less

19
Q

A

Negative to positive

22
Q

What is potential difference

A

It is difference between voltage in 2 components or circuit

23
Q

What is a milivolt

A

0.001 volts

24
Q

What is current measured in

A

Columbs

25
Q

What is emf

A

Electromagnetic force

26
Q

What is a consumer

A

It is any component within a circuit

27
Q

What are the rules of a series circuit

A

Resistance is equal to amount of resistors , and if one device stops working nothing works

28
Q

What are the rules of a parallel circuit

A

Resistance will equal smaller then smallest resistor

29
Q

What wave type does an inductive sensor give out

A

Sine wave it is a smooth up and down

30
Q

How do you check resistance of a component

A

Isolate the component then test using ohms function
