If 17.32v are applied across a resistance of 50 ohms, how much power
is expended in the resistor? - ANSWER-6.0 watts.
Formula: V squared/R = P
17.32 squared (299.98)/50=5.99
Signal range for pneumatics? - ANSWER-3-15psi. 3-6-9-12-15
If transformer primary=120v and secondary 12v=20 amps, what are
the amps on the primary? - ANSWER-2 amps.
Formula:
I =Amps/Volume of current
E = Volts/Force moving the current
P = Watts, Electrical power produced
, I x E=P
12 x 20=240watts
In a transformer watts stay the same so now:
P/E=I
240/120v=2 amps
What happens when a motor loses one phase out of 3? - ANSWER-
Single phasing will cause the motor to trip the overloads
What instrument do you use to measure 4-20 mA? - ANSWER-DC
clamp meter
How do you connect an ammeter to check an electrical circuit? -
ANSWER-In series with the load.
If you are angry or impatient with one worker you should? - ANSWER-
Avoid transferring that feeling to others.
First step in troubleshooting a programmable logic controller (PLC)
system is? - ANSWER-Knowing and understanding the process
Which of the following actions should be taken before working on
controls that may disrupt plant operations? - ANSWER-Have an
operator present.
Which of the following best describes the efficiency of preventive
maintenance for plant equipment? - ANSWER-Periodic inspection of
facilities to discover developing defects that could lead to equipment
failure.
In a 240v-120v Delta system, the high leg is? - ANSWER-208v
