As the ratio of the load resistance to the internal resistance increases, the power dissipated by the internal resistance
decreases.
(A True
(B) False
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.

The human body has many biological system that can be modelled mathematically. Some of these systems are open-loop others are closed loop. Your final report should consider a mathematical model of one of these systems.

- 4. Preface: For this problem we are assuming the voltages are constant (also known as "de" voltages). This isn't actually the case, but, we will later learn that you can treat alternating voltages (such as would actually exist in this scenario) by appropriately scaled constant voltages. Hair dryers have a small motor that runs a fan, plus two heating coils for making the air hot enough to dry hair. The circuit diagram below depicts a hair dryer on the right side (everything to the right of the nodes labeled HOT and NEUTRAL) and it is receiving power by being plugged into a wall socket that provides 120 V (as depicted to the left). One of the heating coils can be switched in or out of operation via the switch S1 shown in the circuit. The resistor R1 ensure that the motor is not damaged by excessive voltage. Note that the model of the motor is a voltage “source” in series with a resistor, but this source will only consume power.
