TOPIC 1: ELECTRICAL SAFETY
7 Questions • 8.6% of Exam • This topic covers fundamental safety concerns and standards related to electrical systems.
QUESTION 1
What does the acronym ESD stand for?
[A] Electrostatic Discharge
[B] Electrostatic Device
[C] Electromagnetic Sensitivity Diac
[D] Electrostatic Damage
Correct Answer: A.
Electrostatic Discharge.
Rationale: The term "Electrostatic Discharge" accurately represents the common phenomenon of a sudden flow of
electricity between two objects at different electrical potentials, caused by a buildup of static electricity. This definition aligns
with the term "ESD" being widely used in electronics and industries to describe the protection of sensitive components from
damage due to static electricity.
QUESTION 2
Current amounts between ______ and _____ can be lethal.
[A] 100mA, 200mA
[B] 10mA, 33.3mA
[C] 33.3, 75.6mA
[D] 4mA, 10mA
Correct Answer: A.
100mA, 200mA.
Rationale: The correct answer is based on the fact that electrical currents above 100mA can cause cardiac arrest by
disrupting the heart's electrical impulses, while currents below 10mA are generally not considered lethal. This is because the
human body's response to electrical shock changes significantly at the 10mA threshold, with higher currents posing a
greater risk of serious harm or death.

QUESTION 3
What is the number one concern in regards to electrical safety?
[A] Proper grounding
[B] ESD
[C] Shock
[D] Faulty equipment
Correct Answer: C.
Shock.
Rationale: Electrical shock is the primary concern in electrical safety because it poses a direct threat to human life by
causing cardiac arrest, burns, or even death. This risk is amplified by the fact that electrical shock can occur without any
visible injury, making it a silent and unpredictable hazard that demands proper precautions and safety measures.
QUESTION 4
Bohr's Atomic Model consists of what three components?
[A] Neutrons, ion, neutrinos
[B] Protons, neutrons and cations
[C] Tachyons gravitons and electrons
[D] Protons, neutrons and electrons
Correct Answer: D.
Protons, neutrons and electrons.
Rationale: Bohr's Atomic Model primarily focuses on the arrangement of electrons in energy levels around the nucleus,
which consists of protons and neutrons. The inclusion of electrons in the model is crucial as they are the particles
responsible for the chemical properties of an atom and occupy specific energy levels, making option D the correct choice.
