=== START OF EXAM ===




SECTION 1: OHM'S LAW & ELECTRICAL THEORY



Question 1

What is the resistance associated with a 1,500-watt appliance connected to a 120-
volt circuit?

A) 9.6 ohms

B) 12.5 ohms

C) 8.0 ohms



1

,D) 15.0 ohms



Correct Answer: A


Rationale: Using Ohm's Law formula: R = V²/P = (120 V)² / 1,500 W = 14,400 /
1,500 = 9.6 ohms .



Question 2

One horsepower is equal to how many watts?

A) 550 watts

B) 746 watts

C) 1,000 watts

D) 2,000 watts



Correct Answer: B


Rationale: One horsepower (hp) is equivalent to 746 watts. This is a fundamental
conversion used in motor calculations .



Question 3

A 3-hp, 240-volt, 3-phase motor has an efficiency of 90% and a power factor of
95%. How many amperes does it draw?

A) 9.2 amperes


2

,B) 6.3 amperes

C) 12.5 amperes

D) 8.0 amperes



Correct Answer: B


Rationale: For 3-phase motors: I = (hp × 746) / (V × √3 × eff × PF) = (3 × 746) /
(240 × 1.732 × 0.90 × 0.95) = 2,238 / (240 × 1.732 × 0.855) = 2,.4 = 6.3
amperes .



Question 4

Approximately how many kilowatts are used by a three-phase, 480-volt AC motor
that draws 52 amperes and has a power factor of 88%?

A) 28 kW

B) 38 kW

C) 48 kW

D) 58 kW



Correct Answer: B


Rationale: kW = (V × I × √3 × PF) / 1,000 = (480 × 52 × 1.732 × 0.88) / 1,000 =
38.0 kW .




3

, Question 5

A resistor has color bands: orange, red, brown, silver (in order). What is the resistor
value?

A) 220 ohms (10%)

B) 320 ohms (10%)

C) 420 ohms (10%)

D) 520 ohms (10%)



Correct Answer: B


Rationale: Orange = 3, Red = 2 (first two digits: 32), Brown = ×10 (third band
multiplier), Silver = ±10% tolerance. Value = 32 × 10 = 320 ohms ±10% .



Question 6

A 3-hp single-phase motor at 240 volts with 83% efficiency draws what current?

A) 8.23 amperes

B) 11.23 amperes

C) 14.23 amperes

D) 17.23 amperes



Correct Answer: B
