When working with a client to design an AV solution for a new conference center, the client
requests a detailed budget for the equipment and installation. In what project phase does this
occur? - answer✔✔Design Phase

When verifying a display system, what should be used to determine whether it meets a specified
contrast ratio? - answer✔✔Spot Photometer
A simple dimmer rack is feeding 24 incandescent lights during a stage production. The rack is
running on a steady 230v AC supply and averaging a current draw of approximately 98 amps.
Suddenly the line voltage drops to 211v AC. Calculate the expected draw at this new voltage. -
answer✔✔90 Amps
The question is to test familiarity with Ohm's Law and the relationships between voltage,
current, and resistance. If the voltage decreases but the load remains constant, than the current
must also decrease. So if the voltage falls from 230 to 211 volts than the current must fall
proportionately. As 211/230=.92 the current drawn will be 98x.92=90.16(90 amps), **Note that
incndescenet lamps are a resistive load, not a constant power load such as an amp or a projector.
The answer would be different with a constant power device.
