Deck 6: Understanding and Using Ladder Diagrams

Question 1

The vertical power lines (rails) of the ladder diagram represent the ____________________ of the circuit.

Answer 1

voltage potential,voltage,potential

Question 2

Describe how contacts associated with relays, timers, motor starts and the like are represented on a ladder diagram.

Answer 2

Contacts associated with relays, timers, motor starters, and the like always have the same number or letter designation as the device that controls them. This labeling method holds true no matter where the contact(s) appear in the circuit.

Question 3

How is a ladder diagram read?

Answer 3

A ladder diagram is read like a book; from left to right and from top to bottom.

Question 4

The wiring diagrams show the circuit in its simplest form.

Question 5

The ____________________ shows the circuit wiring and its associated devices in their relative physical location.

Question 6

Describe voltage potential as depicted in a ladder diagram.

Question 7

The ladder diagram, also referred to as a schematic or elementary diagram, is used by the electrician or technician to speed their understanding of how a circuit works.

Question 8

Devices or components are shown in order of importance whenever possible in a ladder diagram.

Question 9

By combining two NOT gates and an AND gate, we get a NAND gate.

Question 10

The NOT gate is often referred to as a(n) ____________________.

Question 11

Electrical devices or components are shown in their ____________________ condition on a ladder diagram.

Question 12

How is the power required for a control circuit shown on a ladder diagram?

Question 13

The ____________________ has been the "working language" of electricians and electrical engineers for many years.

Question 14

Logic gates can be combined to create very complicated control logic.

Question 15

What are the two basic types of electrical diagrams?
