16
Q

What is a parallel circuit?

A

Circuit that has multiple current paths to flow through

17
Q

What does the term in series mean?

A

Anything connected directly across two points of different potential is said to be in series

18
Q

Anything connected in series has what?

A

Current flow through it unless the resistance is sufficient to prevent it

19
Q

A worker should never do what when doing hot work?

A

Place himself in series

20
Q

What type of equipment is connected in series with the line?

A

Regulators
Reclosers
Sectionalizers
And switches

21
Q

What happens to the current flow when a device is connected further down the line

A

The current will pass through the device witch cause an increase of current flow through them

22
Q

If a certain amount of current flow is required for the circuit what must the voltage be?

A

The voltage must be high enough to maintain the proper current flow

23
Q

In a series circuit is the current high lower or is it the same through the whole circuit

A

The current is the same at any given point

24
Q

What must a transformer do to to maintain the amperage

A

Supply enough voltage

25
Q

What is voltage drop?

A

A certain amount of voltage to push current through a load with a given amount of resistance

26
Q

In a series circuit what will happen to the voltage as it comes across resistance.

A

The voltage will drop

27
Q

What must the voltage drops across all resistors equal ?

A

The voltage applied to the circuit

28
Q

Each section in the over all power system is considered having what?

A

Source
Conductors
And loads

29
Q

What type of circuit is power lines considered having? And why? But what is the layout of the system predominantly considered as?

A

Combination type circuit because of the equipment that is connected in series with the line
Parallel

30
Q

Parallel circuits are considered to have their own source conductors and loads at what point are these sections divided it?

A

Where the voltage is transformed from one level to another

31
Q

When leaving the substation on a transmission line what type of circuit is used? And why

A

Parallel circuit and because each line has its own path to and from the substation of one transmission line goes down the protective equipment will disconnect it from the circuit.

32
Q

Sub transmission substations are what to the transmission line

A

Parallel

33
Q

At each point that the voltage changes a new blank can be viewed

A

Parallel circuit

34
Q

How can you find out that the entire layout is a parallel circuit

A

Point of utilization

35
Q

Circuits are also considered what type of circuit

A

Parallel circuit

36
Q

Each load Connected in a parallel circuit will have what to the applied voltage?

A

Voltage drop

37
Q

Each blank connect to a parallel circuit draws a certain amount of current

A

Device

38
Q

In a parallel circuit as a device is added to the line current flow through the conductors will decrease true or false

A

False the current will increase

39
Q

In order to properly size a line switch fuse what must you do?

A

Determine the current drawn by each load connected to he circuit
The currents are added to find the overall current drawn by the circuit
The sum is then rounded to the next available fuse size
