NACE CP1 BOOK CHAPTERS 1-4 EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
GRADED A++
Power
rate at which energy is used by an electrical device (P=VI, necessary to know power
required by CP rectifier to size AC supply circuit)
Longer wires (series) = ____ resistance and ____ current for given voltage
higher, lower
Cable running to groundbed represents ____ circuit and groundbed itself
represents ____ circuit
series, parallel
DC
direct current (flows in one direction, produced by a battery)
AC
alternating current (reverses direction, hertz represents a cycle)
How can AC be turned to DC?
a rectifier
What is a transformer?
used to increase or decrease voltage or isolate incoming voltage source from outgoing
voltage
, Primary winding of a transformer is connected to...
the voltage source
Secondary winding of a transformer is connected to...
the unit to which voltage is to be supplied
primary voltage / secondary voltage =
# of primary turns / # of secondary turns
In CP rectifiers, taps are located in the ____ winding so that several voltage
adjustments are possible
secondary
Impedance
total opposition that a circuit presents to AC (similar to resistance in a DC circuit, also
depends on frequency and wave shape of current)
D'Arsonval movement
stationary permanent magnet/moving coil system of analog meter
When using an analog meter, what terminal is the reference electrode connected
to?
positive
Voltmeter
measures voltage in response to current flow and series resistance through coil (more
sensitive at lower voltages)
Ammeter
measures current flow with resistors (shunts) in parallel
Ohmmeter
