About this Exam

Prepare with the AMPP CP3 Technologist Practice Questions - AMPP CP3 Cathodic Protection Technologist Exam practice quiz. This question bank includes 100 questions covering design, pipeline, anode, technologist, and current. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.

Sample Questions

Question 1
For a CP system design, what attenuation constant α describes the exponential decay of CP current along a uniformly coated pipeline?
α = sqrt(R_L / R_C), where R_L is pipe longitudinal resistance per unit length and R_C is coating resistance per unit length
α = R_L × R_C
α = R_C − R_L
α = R_L + R_C
Question 2
A pipeline has a longitudinal pipe resistance of 10 microohms/m and a coating resistance of 10,000 ohm·m. What is α?
1.0 /m
1 × 10^-4 /m
1.0 × 10^-2 /m
0.0316 /m
Question 3
Dwight's equation gives the ground resistance of a single vertical anode. The equation is:
R = (ρ / 2πL) × (ln(8L/d) − 1), where ρ is soil resistivity, L is anode length, and d is anode diameter
R = ρ × L
R = ρ / (π × d²)
R = 4π × ρ × L
Question 4
Which of the following standards is the primary reference for CP design for AST tank bottoms (external)?
NACE SP0285
API RP 651 / NACE RP0193
NACE SP0388
NACE SP0290
Question 5
For designing CP for a 10 km new bare steel pipeline in 3,000 ohm-cm soil, what is a reasonable first-pass current requirement estimate, assuming ~10 mA/m² for bare steel?
Approximately 100 mA total
Approximately 50 A total (assuming ~5000 m² surface area for a 12-in pipe)
Approximately 5 A total
Approximately 5,000 A total
