Basic Electricity

Question 1

What is potential difference

Answer 1

Potential difference is commonly referred to as voltage. This is the force or pressure which causes electrons to move through a circuit. The letters E and V represent voltage

Question 2

What are the six known methods of producing voltage

Answer 2

• friction
• pressure
• heat
• light
• chemical action
• magnetism

Question 3

What is current

Answer 3

Current is the movement of electrons within a circuit. Amperage is the term used to measure this movement across certain points of a circuit. The letter I or A represent current

Question 4

What is resistance

Answer 4

Resistance is the opposition of current flow. Ohms is the unit used to measure this resistance.

The letter R or the Omega symbol

Question 5

What are some factors that determine resistance

Answer 5

• diameter
• length
• temperature
• materials

Question 6

What are the components of an electrical circuit

Answer 6

• power source
• load
• conductor
• switch control element

Question 7

What is a series configuration

Answer 7

Hey Siri circuit has but one path for the current to flow. Current is the same at all points

Question 8

What is parallel configuration

Answer 8

A parallel circuit is a circuit that has More than one path for the current to flow. the current divides equally

Question 9

What is a series parallel configuration

Answer 9

A series parallel circuit may have multiple loads in parallel and a load or loads in series.

Question 10

What are the two classifications of batteries

Answer 10

Batteries are composed of two or more basic units called cells, classified as either primary or secondary

Question 11

What is a primary cell

Answer 11

A primary cell consist of carbon and zinc rods called electrodes.

The most useful type of primary cell is the dry cell.

Question 12

What happens to batteries connected in a series

Answer 12

Batteries in series will increase voltage and the amperage will remain the same

Question 13

What happens to batteries connected in a parallel

Answer 13

Batteries in parallel will increase amperage and voltage will remain the same

Question 14

What is a secondary shell

Answer 14

Secondary cells are normally used in rechargeable systems. They are similar to primary. To come in types are lead/acid used in vehicles, and nickel/cadmium used in rechargeable dry cell batteries

Question 15

What is the purpose of a capacitor

Answer 15

A capacitor stores electrons

Question 16

What does PAN stand for

Answer 16

Percussion actuated non-electric disruptor

It is also capable of impacting two or more targets inside the bomb with an isochronicity of 500 microseconds or less

Question 17

What type of command initiation does the PAN disruptor use

Answer 17

Shock tube

Question 18

what type of ammunition does the PAN disruptor use

Answer 18

It uses standard 12 gauge shotgun shells, blanks and special modified loads

Question 19

What are the two general disruption concepts

Answer 19

General disruption
Specific disruption

There could be scenarios where a combination of general and specific disruption is required

Question 20

What is a general disruption

Answer 20

The general disruption consist of shooting into a general area of the device without specific target acquisition. This concept is that the projectile, usually water, will open the package, disrupt the explosives and firing train. This technique may function a bomb

Question 21

What is precise disruption

Answer 21

Precise disruption consist of attacking a specific component or area of the device. These components are generally the power source and wires.
