About HVAC exam

Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

HVAC CERTIFICATION
For aspiring heating, ventilation, and air conditioning (HVAC) specialists, pursuing certification can be a way to show one’s competencies to prospective employers or clients. These credentials can demonstrate a wide range of skills in the field such as: installing, repairing, and maintaining HVAC units in residential or commercial spaces; analyzing air quality, humidity levels, and temperature control mechanisms; understanding the fundamentals of heating and refrigeration systems.

HOW TO BECOME A CERTIFIED HVAC TECHNICIAN
Some job-ready HVAC programs include the certification process as part of their training program such as the one at North American Training Center. That said, there is a wide array of agencies offering HVAC certifications for those looking to enhance their credentials. The North American Technician Excellence (NATE) hosts the “industry competency exam” and provides a number of HVAC-R specialty certifications such as air distribution (AD), HVAC efficiency analyst (senior level), and HVAC performance verifier. HVAC Excellence not only provides program accreditation, but has employment-ready certification exams for air conditioning, light commercial air conditioning, and basic refrigeration and charging procedures. The Refrigeration Service Engineers Society (RSES) has a partnership with NATE and provides additional certification exams including EPA section 608, commercial air conditioning, commercial refrigeration, heating, and HVAC-R electrical.

Question 7, the total resistence 1/Rt= 1/24+1/60/+1/40... Rt= 12 ohm

[ChristianInfidel]

On question 7, total resistance should be A: 12 Ohms. The law state it must be less than the smallest resistor which is 24 Ohms, the only answer less than 24 is A. YOu show the answer is B:24 ohms
