FINAL EXAMINATION: ELECTRICITY:
PRINCIPLES AND APPLICATIONS (9TH ED.)
BY RICHARD J. FOWLER
Part I: True or False (30 Questions)
Instructions: Indicate whether the statement is True (T) or False (F).
1. T / F Electrostatic charge refers to electrical charge that is in
motion.
2. T / F Voltage is the measurement of the difference in charge
between two points .
3. T / F A lock can have more than one key (in the context of key-
operated switches).
4. T / F Polarity is a critical factor when using an ohmmeter to
measure resistance.
5. T / F One alternation of a sine wave occurs within 180 degrees .
6. T / F In an inductive circuit, current leads voltage by 90 degrees
(ELI the ICE man) .
7. T / F A standard copper conductor will have higher resistance at
a lower temperature.
8. T / F Fuses can usually handle a momentary surge (like motor
starting) of 3x rated current for a few seconds .
,9. T / F A single conductor in a residential branch circuit is allowed
to operate at 100% of its 15A rating continuously.
10. T / F Piezoelectric igniters are commonly found on gas
burners and grills .
11. T / F A thermocouple generates electricity by using light
(photovoltaic effect).
12. T / F The time required for one complete alternation (half-
cycle) is known as the period .
13. T / F If a clamp-on ammeter reading is too low, you can loop
the wire through the clamp multiple times to get an effective
reading .
14. T / F Inductance is the opposition to any change in
current .
15. T / F Current in a series circuit remains constant
throughout all components.
16. T / F Carbon composition resistors are generally more
stable and accurate than metal film resistors.
17. T / F A short circuit results in abnormally low resistance,
causing high current flow.
18. T / F Flux lines leave the North pole of a magnet and enter
the South pole .
19. T / F A capacitor blocks DC and allows AC to pass more
easily as frequency increases.
, 20. T / F Power factor (PF) is the ratio of Apparent Power (VA)
to True Power (Watts).
21. T / F A transformer can step up voltage without stepping
down current (power is gained).
22. T / F RMS voltage is equal to the peak voltage multiplied by
0.707 .
23. T / F In a purely capacitive circuit, the voltage lags the
current.
24. T / F A megohmmeter is used specifically to measure low
resistance values in circuit breakers .
25. T / F Conductors have a large number of free electrons
compared to insulators.
26. T / F Kirchhoff’s Voltage Law states that the sum of
voltage drops around a closed loop equals zero.
27. T / F Class 0 electrical gloves are rated for voltages up to
1000V .
28. T / F Open circuit voltage is measured when the circuit is
fully operational and current is flowing.
29. T / F Silver is a better conductor than copper.
30. T / F A circuit breaker protects the circuit by detecting
heat or magnetic fields caused by overcurrent.
