Spot Photometer - answers✔✔When verifying a display system, what should be used to
determine whether it meets a specified contrast ratio?
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. - answers✔✔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.
