Q

What are the rules for a series and parallel circuit?

A

In a series circuit, the voltage across the circuit is the sum of the voltages across each component. The current ( amperage ) is the same through each component.
In a parallel circuit, the voltage across each of the components is the same. The total current ( amperage ) is the sum of the currents through each component.

Q

What are the 6 sources of Voltage?

A

• Light= The process through which a solar cell converts sunlight into electricity
• Pressure ( Piezoelectricity ) = Produced from crystalline materials, (eg: propane cook top ignitor)
• Induction = Relationship between electricity & magnetism
•Heat = Causes electrons to flow in a conductor (eg: Burning wood, the sun)
•Chemical = Action on cell plates that maintains electron flow (eg: batteries )
•Friction = Rubbing two materials together ( eg: Static shock, Match book)

35
Q

Code 5.12.11 Overcurrent Protection

A

•5 Amp - 18 AWG
•10 Amp - 16 AWG
•15 Amp - 14 AWG
•20 Amp - 12 AWG
•30 Amp - 10 AWG
•40 Amp - 8 AWG
•50 Amp - 6 AWG

36
Q

What is a Schematic Diagram?
( Ladder Diagram )

A

•Ladder diagram is the simplest form of schematic diagram
•Shows circuit components on horizontal or vertical lines regardless of location
•Ladder diagrams are used for troubleshooting
•Can be drawn from top, bottom, left to right, or vise versa.

37
Q

What are electrical diagrams?

A

Electrical diagrams are a common method of depicting electrical circuits.
There are 4 types of diagrams:
• Schematic
•Wiring diagrams
•Block diagrams
• Pictorial Diagrams

38
Q

USB Charger

A

•Charging stations provide 5.0 VoltDC
•Used to power or charge electronic devices
•Test using a voltmeter or a USB tester

39
Q

Ohm ( R )

A

Base unit for the measurement of resistance or opposition to electron flow.

40
Q

Watt ( W )

A

Base unit for the measurement of electrical power consumption.
1 Watt = 1 Volt x 1 Ampere

41
Q

Ohm’s Law

A

It takes one volt of potential to move one ampere of current through one ohm of resistance.

42
Q

Voltage drop in a series circuit will…

A

Always add up to the total volts

43
Q

What is voltage drop ( VD )

A

Voltage is used up when current flows through a resistance.

44
Q

Relays

A

Low amperage control circuit controls a higher amperage load circuit

45

Wiring Diagram

A

•Emphasizes connection between elements of a circuit or system
•Use horizontal and vertical lines to represent the wires
•Uses simplified pictorials that clearly resemble circuit / system components
•Equipment and wiring are placed on the drawing to approximate the actual physical location in a real circuit

51
Q

DC Electrical Systems

In DC circuit theory, electrical current is the movement or flow of electrical charge and is measured in amperes for intensity.
It is the continuous and uniform flow of electrons ( negative particles ) around a circuit that are being pushed by the voltage ⚡️ source

53
Q

A

Orderly arrangements of atoms

54
Q

Current

A

• Lack detailed information about the layout & connections in a circuit

58

A

•Shows the circuit in detail ( as they really look )
•Indicates how the wiring is attached
•Pictorial diagram can be used to locate components in a complex system

A

•Protons
•Neutrons
•Electrons

62
Q

What is a semiconductor?

A

•4 electrons in outer valance
•Has some characteristics of both insulators & conductors

Q

Electron Theory

A

Used for electronics

Negative to positive

67
Q

What is Hertz?

A

Speed of frequency of voltage per second
AC sign wave moves at 60 Htz per second

68
Q
