CTS EXAM - AV MATH WITH ALL CORRECT & 100%
VERIFIED ANSWERS|UPDATED TO PASS
Aspect Ratio ✔Correct answer-The ratio of width to height in a screen or other output device. W/H
Throw Distance ✔Correct answer-The distance from a projector to a focusing surface or screen. =
Screen Width * Throw Ratio
Image Height Formula ✔Correct answer-SH = D / SL SL = 4, 6, or 8
ex. D = 480inches
SL = 8
SH = = 60in high
Farthest Viewer By Text Height ✔Correct answer-D = TH * 150
Impedance ✔Correct answer-Total opposition to current flow.
Parallel Circuit Impedance Formula (Same Impedance) ✔Correct answer-ZT = Z / N
Z = impedance
N = quantity of loudspeakers
Parallel Circuit Impedance Formula (Different Impedance) ✔Correct answer-ZT = 1/(1/Z1 + 1/Z2 +
1/Z3....1/ZN)
Series Circuit Impedance Formula ✔Correct answer-ZT = Z1 + Z2 + Z3 ... ZN
Decibel Formula For Distance ✔Correct answer-dB = 20 * log (D1/D2)
Decibel Formula For Voltage ✔Correct answer-dB = 20 * log (V1/V2)
Decibel Formula For Power ✔Correct answer-dB = 10 * log (P1/P2)
Inverse Square Law For Light ✔Correct answer-If the distance is doubled then the total area
becomes four times as large. Energy becomes one-fourth of its original intensity.
Inverse Square Law For Sound ✔Correct answer-As distance doubles the sound pressure level is
lowered by 6dB. Energy becomes one-fourth of its original intensity.
Ohms Law ✔Correct answer-The relationship between current, voltage, and resistance in an
electrical circuit
Current ✔Correct answer-The rate of electrons flowing through a circuit per second. Measured in
amperes and It is typically represented in math by "I" for "intensity" or "A" for "amperes."
Voltage ✔Correct answer-The electrical potential to create current flow in a circuit. It is
represented in math by the letter "V" for "volts" or "E" for "electromotive force."
