D

Question 2

Primary cells are used for storage batteries.

Accepted Answer

Primary cells are single-use batteries that cannot be recharged, whereas storage batteries are rechargeable and thus are considered secondary cells.

Question 3

A lead acid battery changes its chemical properties in different states.

Accepted Answer

A lead acid battery undergoes chemical reactions in different states of charge, which affect its performance and overall health.

Question 4

What is the behavior of the Nickel Cadmium, Pocket Plate Liquid Electrolyte battery at elevated temperatures?

Accepted Answer

The answer of What is the behavior of the Nickel...

Question 5

No one knows when the first battery was invented.

Accepted Answer

The exact date and inventor of the first battery are not known, but the earliest known batteries are the Baghdad Batteries, believed to date back to the Parthian or Sassanid periods (between 250 BCE and 224 CE). However, the true purpose and origin of these artifacts remain a subject of debate among historians and archaeologists.

Question 6

What did the original voltaic pile consist of?

Accepted Answer

The answer of What did the original voltaic pile consist...

Question 7

Benjamin Franklin, in 1748, strung together several Leyden jars as ____ and called the array a "Battery".
A) inverters
B) transformers
C) capacitors
D) resistors

Accepted Answer

Leyden jars are a type of capacitor, which store electric charge. Benjamin Franklin strung several of these capacitors, or Leyden jars, together to create a battery.

Question 8

The parallel circuit is used to increase the circuit ____.
A) current
B) voltage
C) resistance
D) density

Accepted Answer

In a parallel circuit, the current has multiple paths to flow through, which reduces the overall resistance in the circuit. This allows for an increase in the total current flowing through the circuit.

Question 9

What types of batteries exist?

Accepted Answer

The answer of What types of batteries exist?...

Question 10

What battery is most used in backup systems in the United States?
A) Lead Acid/Antimony
B) Lead Acid/Calcium
C) Lead Acid/Plante'
D) Lead Acid/Calcium, Maintenance free Liquid Electrolyte

Accepted Answer

Lead Acid/Calcium batteries are commonly used in backup systems due to their maintenance-free nature and reliability.

Question 11

A battery is typically rated in ohms.

Accepted Answer

A battery is typically rated in volts, not ohms. Ohms refer to the measure of electrical resistance.

Question 12

What is the primary purpose of a series circuit in a battery system?

Accepted Answer

The answer of What is the primary purpose of a...

Question 13

John Daniell did experiments in an attempt to improve the voltaic battery.

Accepted Answer

John Daniell was a British chemist who did experiments to improve the voltaic battery. He invented the Daniell cell in 1836, which was an improved version of the voltaic cell that produced a more stable electric current.

Question 14

What battery can be used in an office environment or in a unventilated room?
A) Lead Acid/Antimony
B) Lead Acid/Calcium
C) Lead Acid/Calcium, Maintenance free Gelled Electrolyte, Sealed
D) Lead Acid (Special Alloy), Suspended Electrolyte, Maintenance free, Sealed

Accepted Answer

The answer of What battery can be used in an...

Question 15

A cell consists of a negative electrode (anode); an electrolyte, which conducts ions and a positive electrode (____).
A) code
B) cathode
C) mode
D) manode

Accepted Answer

In a cell, the positive electrode is called the cathode, as it is the site of reduction (the opposite of oxidation, which occurs at the anode). None of the other options listed are correct terminology for the positive electrode in a cell.

Question 16

NEC 690.14 (C-2) requires that each disconnecting means in a photovoltaic system shall be permanently marked to identify it as a ____.
A) photovoltaic disconnect
B) photovoltaic ground fault
C) photovoltaic circuit
D) photovoltaic circuit breaker

Accepted Answer

NEC 690.14 (C-2) specifically requires that the disconnecting means be marked as a "photovoltaic disconnect." None of the other options listed are specified in this code section.

Question 17

The ratio of the weight of a given volume electrolyte to an equal volume of water is known as ____.
A) concentration
B) specific density
C) specific gravity
D) strength

Accepted Answer

The ratio of the weight of a given volume electrolyte to an equal volume of water is known as specific gravity. Specific density and strength are not applicable in this context. Concentration may refer to the amount of solute dissolved in a given amount of solvent.

Question 18

What battery is selected where frequent discharging is expected?
A) Lead Acid/Plante'
B) Lead Acid/Calcium
C) Lead Acid/Calcium, Maintenance free Liquid Electrolyte
D) Lead Acid/Antimony

Accepted Answer

Lead Acid/Antimony batteries are designed to handle frequent discharging and recharging cycles, making them suitable for applications where this is expected.

Question 19

In 1836 John Daniell invented a primary cell in which ____ was eliminated in the generation of electricity.
A) oxygen
B) nitrogen
C) carbon
D) hydrogen

Accepted Answer

John Daniell invented a primary cell that eliminated hydrogen in the generation of electricity. This was achieved by using a copper sulfate solution and a zinc sulfate solution, which prevented the buildup of hydrogen gas at the electrodes, a common problem with earlier designs like the Voltaic pile.

Question 20

List the two types of charge controllers.

Accepted Answer

The answer of List the two types of charge controllers....
