In the circuit of the figure 8 = 3.30 kV, C = 8.60 UF, R1 = R2 = R3 = 1.05 MQ. With C completely uncharged, switch S is suddenly closed (at t = 0). At t = 0, what are (a) current i, in resistor 1, (b) current i2 in resistor 2, and (c) current is in resistor 3? At t = co (that is, after many time constants), what are (d)i1, (e)i2, and (f)is? What is the potential difference V2 across resistor 2 at (g)t = 0 and (h)t = co? 18 (a) Number Units (b) Number Units (c) Number Units (d) Number Units (e) Number i Units(f) Number Units (g) Number Units (h) Number UnitsYour answer is partially correct. A copper wire of radius a = 0.204 mm has an aluminum jacket of outer radius b = 0.303 mm. There is a current i = 2.41 A in the composite wire. Take the resistivity for copper and aluminum to be 1.69 x 10-80-m and 2.75 x 10-80-m. Calculate the current in (a) the copper and (b) the aluminum. (c) If a potential difference V= 13.4 V between the ends maintains the current, what is the length in meters of the composite wire? (a) Number i 6.166 Units A (b) Number i 10.1 Units A (c) Number i Units mIn the gure battery 1 has emf $1 = 40.0V and internal resistance r1 = 0.034 D and battery 2 has emf (2 = 400 V and internal resistance r2 = 0.029 n. The batteries are connected in series with an external resistance R' [a] What R value makes the terminal-to- terminal potential difference of one of the batteries zero? lb] Which battery is that?
