How does the power, P, dissipated by a resistor depend on the indicated parameter (resistance, R, of the resistor, or the voltage or current of the supply) for each of the following scenarios? I am looking for a mathematical equation for power as a function of the indicated parameter followed by a description of the dependence - does the power increase, decrease, remain the same or some other dependence, as the parameter is increased? (and if other, describe.) If it is increasing or decreasing, by what factor does the power change if the parameter is increased by a factor of 3? (a) Constant R, powered by ideal voltage supply (We will examine real batteries that have internal resistance in class and the next homework.) How does P depend on the voltage, V, of the supply? (b) Constant R, powered by ideal current supply. How does power depend on the current I? (c) Ideal battery operating at a fixed voltage, powering a variable resistor R. How does P depend on the resistance, R, of the resistor? (d) Ideal current source operating at a fixed current, powering a variable resistor R. How does P depend on the resistance, R, of the resistor?

Suppose the wire has a 10Ω resistance (which is almost certainly an overestimate) and the voltmeter has a 1MΩ resistance (1Ω=1s/F). Given that our capacitances are of order ~10μF, compute the time constant for each resistance: this is essentially the time it takes for current to "go through" that component. From these timescales, consider: of the two processes described above (the quick change in voltage and the slow change in voltage), which process is controlled by each component's resistance? On very long timescales (minutes-to-hours), the voltmeter can essentially be considered as another wire - current can pass through it given enough time. Based on this, if we were to leave the capacitors in Part I in the left (capacitors charged) position for a very long time, what voltages would you observe on each capacitor? What if we left the capacitors in Part II in the right (capacitors connected together) position for a very long time?
Equation P = I2R Seems to suggest that rate of increase of internal energy in a resistor is reduced, if the resistance is made less. Equation P = V2/R seams to suggest just the opposite. How do you reconcile this apparent paradox?

We have referred to resistorsdissipat-ingheat, i.e., we have assumed thatP=I∆V is always greater than zero. Could I∆V come out to be negative for a resistor? If so, couldone make a refrigerator by hooking up a resistorin such a way that it absorbed heat instead ofdissipating it?
I have a non-ohmic resistor that is modeled by I=AeBV, and I was asked to calculate the resistance at 4.5V using the formula R=dV/dI. I'm confused as to how to set this up.
