A 240V, 24A, SINGLE-PHASE LOAD IS LOCATED 160 FT FROM THE PANELBOARD. THE LOAD IS
WIRED WITH 10 AWG CONDUCTORS. WHAT'S THE APPROXIMATE VOLTAGE DROP OF THE
BRANCH-CIRCUIT CONDUCTORS?



A. 3.2V

B. 4.25V

C. 5.9V

D. 9.5V

CORRECT ANS: D. 9.5V



VD = (2 X K X I X D)/CMIL

K = 12.90, COPPER

I = 24A

D = 160 FT

CMIL = 10,380

VD = (2 WIRES X 12.90 X 24A X 160 FT)/10,380 CMIL

VD = 9.50V




DURING NORMAL OPERATION OF A TYPICAL 120-VOLT APPLIANCE CIRCUIT, CURRENT FLOWS
THROUGH THE HOT, GROUNDING, AND NEUTRAL CONDUCTORS.



A. TRUE

B. FALSE

, CORRECT ANS: B. FALSE




AN RLC SERIES CIRCUIT HAS AN APPLIED VOLTAGE OF 240 VOLTS. R = 48 Ω, XL = 100 Ω, XC = 36
Ω, AND Z = 80 Ω. WHAT IS THE TOTAL CURRENT?



A. 1 A

B. 2 A

C. 3 A

D. 4 A

CORRECT ANS: C. 3 A



240/80 = 3




WHAT'S THE DIRECT-CURRENT RESISTANCE OF A 6 AWG COPPER CONDUCTOR THAT'S 400 FT
LONG?



A. 0.20 OHMS

B. 0.30 OHMS

C. 0.40 OHMS

D. 0.50 OHMS

CORRECT ANS: A. 0.20 OHMS



6 AWG RESISTANCE = 0.491 OHMS/1,000 FT [CHAPTER 9, TABLE 8]

(0.491 OHMS/1,000 FT) X 400 FT = 0.1964 OHMS
