Transcribed Image Text: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).

(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 what we have seen in a couple of
other instances where it appears parts of the circuit are mostly, but not completely, decoupled
from each other.

- You have been sent to a new home. The homeowner reports that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it Upon examination, you find that the furnace contains three 5000-W heating elements designed to turn on in stages. For example, when the thermostat calls for heat, the first 5000-W unit turns on. After some period of time, the second unit will turn on, and then, after another time delay, the third unit will turn on What do you think the problem is, and what would be your recommendation for correcting it?
