Question

All the lamps from Lamp #1 to Lamp #7 are designed to work with a nominal Voltage Vlamp of 120V and their resistance Rlamp is constant and do not depends on the temperature. Using this information solve the questions below.

The Channel 2 has four lamp connected as shown in the Figure 2 and again you want to be sure that will not be a black-out in the middle of the performance. Please determine if the Channel 1 can work using the variable ALPHA from 0% to 100%. Yes/No, justify your answer with your calculations. No justifications – No points

Part C
You are the light technician of the performance. The Director ORDERED you (you do not have a
choice!!!) to use the two channel Dimmer PPQQ2019. Every channel has a Maximum Current Imax=30
Amps, and the Voltage in the output of the channel depends of the Variable ALPHA (your control slide!)
that changes from 0% to 100% following this NON LINEAR relation
(ALPHA)?
Vout (ALPHA) = 120 Volts *
10000
Also the Director requested tom place the seven lamps (Lamp 1 to Lamp 7) in the configuration
presented below.
