2.1) In the system presented above, calculate the minimum value of the Imax of the breaker marked
Imax= ?? to ensure that the two channels will work at the maximum of their capacity.
2.2) You have at your disposal lamps which nominal value are 120Volts and the nominal power are
multiple of 300 Watts (e.g. 300W, 600W, 900W, 1200W, etc.). Select the lamps L1, L2, L3, L4 and L5 that
will ensure that the two channels Ch1 (Channel 1), and Ch2 (Channel 2) are working at the maximum of
their capacity. Justify your selection with your calculations.
2.3) Using the following lamps: L1=L2=L3 (120V, 1200W) and L4=L5 (120V 1800W), and assuming that
the resistances of the lamps do not change with the temperature, calculate the current of the system
Isystem when Vout Ch1 = 60 Volts and Vout Ch2 = 90 Volts
2.4) Using the lamps you selected, and assuming that the resistances of the lamps do not change with
the temperature, calculate the Voltage of the Channel 2 Vout Ch2, that will ensure that when Vout Ch1
= 75Volts, the current of the system Isystem will be 40 Amperes
