Hi, Here's my question. 26.45: An emf source (e=120 V), a resistor (R=80.0 W), and a capacitor (C=4.00 mF) are connected in series. As the capacitor charges, what is the magnitude of the charge on each plate of the capacitor when the current in the resistor is 0.900 A? Hint: From the information given, first calculate the voltage across the capacitor when the 0.900 A current flows in the circuit. Then use the voltage as a function of the time equation for a charging capacitor in an R-C circuit.

The student engineer of a campusradio station wishes to verifythe effectiveness of the lightningrod on the antenna mast(Fig. P18.57). The unknownresistance Rx is between pointsC and E. Point E is a “trueground” but is inaccessible fordirect measurement because the stratum in which it is located is several meters belowEarth’s surface. Two identical rods are driven into the groundat A and B, introducing an unknown resistance Ry. The procedurefor finding the unknown resistance Rx is as follows. Measureresistance R1 between points A and B. Then connect Aand B with a heavy conducting wire and measure resistance R2between points A and C. (a) Derive a formula for Rx in terms ofthe observable resistances R1 and R2. (b) A satisfactory groundresistance would be Rx < 2.0 Ω. Is the grounding of the stationadequate if measurements give R1 = 13 Ω and R2 = 6.0 Ω?

How many different resistance valuescan be created by combining three unequal resistors? (Don’t count possibilities in which not allthe resistors are used, i.e., ones in which there iszero current in one or more of them.)
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?
