RATED CORRECT WITH 100% SURE
PASS|GRADED A+
A judgment - CORRECT ANSWERS An opinion is
Easy to use - CORRECT ANSWERS Which of the following is a future of a product or service
A truth - CORRECT ANSWERS A fact is
Saves time - CORRECT ANSWERS Which of the following is a benefit of a product or service
DOT - CORRECT ANSWERS Which of the following agencies has jurisdiction over the shipping
and labeling of refrigerant cylinders?
The flow of electrons through a conductor - CORRECT ANSWERS Electricity is
Electrical pressure - CORRECT ANSWERS Voltage in an energized electrical circuit can be
thought of as
A current will be induced in that conductor - CORRECT ANSWERS If a conductor is moved
through a field of magnetic flux,
It divides across each of the loads - CORRECT ANSWERS What happens to the voltage in a
series circuit
, With an ammeter - CORRECT ANSWERS How is current flow measured in an electrical circuit
A magnetic field will be established around that conductor - CORRECT ANSWERS Whenever
current flows through a conductor
1/1,000,000 of an ampere - CORRECT ANSWERS A microampere is
.90 Because formula (V•A = Watts/638)
So (6•118= 708 so 638/708= .90 - CORRECT ANSWERS Given a 1/2 HP blower motor that
draws 6 A and 118 V during operation. A watt meter is then connected and shows a reading of 638
Watts. What is the power factor for the circuit
20.45 - CORRECT ANSWERS Given a domestic hot water heater with 4,500/4,500 watt
elements and non-simultaneous. What is the anticipated amp draw on an energized element when 220
V is read at that element?
Acts as a conductor in one direction and as an insulator in the other direction - CORRECT ANSWERS
A diode in an electronic circuit
To keep it at zero potential - CORRECT ANSWERS Why are the frames of electrical device is
grounded
Schematic wiring diagram - CORRECT ANSWERS Which of the following electrical diagrams
would a service technician use for troubleshooting a system?
Protects users from dangerous ground faults - CORRECT ANSWERS A GFCI is an electrical
device that?
