Which section of the Ohm’s Law chart should be used to calculate values expressed in Ohms? Select the answer by clicking anywhere within the correct quadrant.
Correct Answer: Ohm’s Law is a fundamental principle used in electrical engineering and physics to describe the relationship between voltage (V), current (I), resistance (R), and power (P). The Ohm’s Law chart is divided into four quadrants, each representing different formulas and relationships among these quantities.
To calculate values expressed in Ohms (which represent resistance, R), you should use Quadrant D.
This quadrant contains formulas that solve for resistance (R), using various combinations of voltage
(V), current (I), and power (P):
R=VIR = frac{V}{I}R=IV
R=V2PR = frac{V^2}{P}R=PV2
R=PI2R = frac{P}{I^2}R=I2P
These formulas are derived from Ohm’s Law and the power equations, providing different ways to calculate resistance based on the available information.
Reference: Ohm’s Law: Explains the relationship between voltage, current, and resistance.
Power Formulas: Derived from the basic Ohm’s Law equations and used to relate power with resistance, voltage, and current.
To further verify and detail the usage of Ohm’s Law chart, you can refer to Axis Technology Specialist documentation or any standard electrical engineering textbooks which provide detailed explanations of these formulas and their applications.

Question #7
Assuming that the speakers in the picture on the LEFT are 8 Q drivers, what is the impedance of the speaker system on the left?
- A . 2Q
- B . 4Q
- C . 8Q
- D . 16 Q
Correct Answer: A
A
Explanation:
Assuming the speakers on the left are 8Ω drivers and they are connected in parallel, the total impedance ZtZ_tZt can be calculated using the formula for parallel resistance:
Zt 1=Z1 1+Z2 1
For two 8Ω speakers in parallel:
1Zt=18+18=28=14frac{1}{Z_t} = frac{1}{8} + frac{1}{8} = frac{2}{8} = frac{1}{4}Zt1=81+81=82=41 Therefore,
Zt=4ΩZ_t = 4ΩZt=4Ω
If the wiring in the diagram shows two pairs of 8Ω speakers connected in parallel, the total impedance is 4Ω for each pair, and if these pairs are then connected in parallel again, the final impedance is:
1Zt=14+14=24=12frac{1}{Z_t} = frac{1}{4} + frac{1}{4} = frac{2}{4} = frac{1}{2}Zt 1 =41 +41 =42 =21
Thus, the total impedance is 2Ω.

Question #61
After installation, the system does not pass audio.
Based on the information in the drawing, what is the MOST LIKELY cause?
- A . cable lengths
- B . system needs a DSP
- C . phantom power is required
- D . speaker requires a 70 V transformer
Correct Answer: C
C
Explanation:
The microphone in the setup may require phantom power to operate. Phantom power is a DC voltage (usually 48V) supplied through the microphone cable to power condenser microphones. Without phantom power, a condenser microphone will not function, resulting in no audio being passed through the system. Since the drawing shows a microphone connected to a digital audio transmitter, it’s likely a condenser microphone, and if it isn’t receiving phantom power, this would be the most probable cause of the system not passing audio.

Question #70
Which of the following is the BEST service when new firmware is available for installed equipment across a fleet of conference rooms?
- A . keeping current version
- B . replacing the equipment
- C . updating them all at once
- D . a ringed update approach
Correct Answer: D
D
Explanation:
The ringed update approach is the best service when new firmware is available for installed equipment across a fleet of conference rooms. This approach involves updating the firmware in phases or "rings," starting with a small group of devices to ensure that the update is stable and does not introduce new issues. Once the initial ring is confirmed to be successful, the update is gradually rolled out to additional groups, reducing the risk of widespread problems. This method allows for controlled testing and monitoring, ensuring that any issues can be addressed before the update is applied to all devices.
