can someone help me with this problem and explain the concepts step by step
4. Again assume each channel of our power supply can provide 30 V and we want to run a 60 V hair dryer motor. So, we again put the two channels in series for double the voltage. But, if you try this with a non-isolated supply, bad things will happen. Don't do that. The following depicts a circuit where internally the supplies have a common ground (i.e., they are not isolated). Non-Isolated Power Supply Droop2 ww 1mQ Channel2 30V 3.3A max Channel1 30V 3.3A max Droop1 1mQ I I I 1 I Red 1 I 1 Black Red Black JumperCable 26mQ 15A max Motor 1200 Needs -60V (a) Show that the current through the jumper cable will greatly exceed its current rating (which, as shown in the schematic, is 15 A). If this happens for more than a very short time, it will melt. (b) Show that the current through Channell greatly exceeds its maximum current rating. If the short circuit protection circuitry doesnt activate quickly, you will fry your power supply. Hint: You can redraw the circuit in a manner similar to…
