Question 1: Amplifier Power Calculation

An audio amplifier outputs 28 volts RMS into an 8-ohm loudspeaker.

What is the approximate power delivered to the speaker?

A) 49 W
B) 98 W
C) 196 W
D) 392 W

Answer: 98 W

Step-by-step:

P = V² / R
P = 28² / 8
P = 784 / 8
P = 98 W

Exam Insight:

When voltage and resistance are provided, the CTS exam expects you to immediately recognize the correct power formula.

Common Trap:

Many candidates attempt to use P = V × I. If current is not provided, this is not the correct approach.

Question 2: Change Management Scenario

During an AV project, the client informally requests a different control interface layout just before installation begins.

What is the BEST next step?

A) Update the interface design to meet the client’s request
B) Document the request and initiate the change process
C) Update the interface design and submit for client approval
D) Document the request and initiate a formal change order

Answer: Document the request and initiate a formal change order

Exam Insight:

Any change to project scope must follow a structured process: document → evaluate → approve → implement.

Common Trap:

Jumping directly to implementation without documentation creates risk and breaks proper project control procedures.

This is exactly how the CTS exam evaluates decision-making — not just technical knowledge.
