Glossary of Terms V

Question 1

Parallel Circuit

Answer 1

An electrical circuit that has more than one path for current to flow by the arrangement of electrical load devices where all positive terminals are joined together and all negative terminals are joined together so that each load device has its own path across-the-linr.

Question 2

Series Circuit

Answer 2

An electrical circuit that has only one path for current to flow by the arrangement of electrical load devices on a single path where negative terminals are joined by the positive terminal of the next device so that each load device is inline with each other.

Question 3

Ohm’s Law

Answer 3

Mathematical formula discovered by George Simon Ohm that describes the relationship between voltage, current and resistance in an electrical circuit.

Question 4

Armature

Answer 4

The part of an electric motor, generator, or relay which is moved by magnetism.

Question 5

Chatter

Answer 5

Noise produced from the rapid opening and closing of a set of contacts.

Question 6

Control Circuit

Answer 6

Circuit that controls a load in main circuit

Question 7

Current Relay

Answer 7

Relay that opens or closes in a circuit by acting to a change of current flow in a circuit

Question 8

Main Circuit

Answer 8

The circuit of a piece of equipment that contains load devices controlled from another circuit

Question 9

Core

Answer 9

Iron center in the wire coil of a transformer

Question 10

Eddy Current

Answer 10

Induced currents flowing in an iron core of smaller circular flows of electricity that moves contrary to the main flow
