Question

In the circuit of the figure 8 = 3.00 kV, C = 8.70 R1 = R2 = R3 = 1.01 M. With C completely uncharged, switch S is suddenly closed (at t = 0). At t = 0, what are (a) current /1 in resistor 1, (b) current i2 in resistor 2, and (c) current /3 in resistor 3? At t (that is, after many time constants), what are (d)i, (e)i2, and (f)i3? What is the potential difference V2 across resistor 2 at (g)t-0 and (h)t - 0? R2 (a) Number (b) Number (c) Number (d) Number (e) Number (f) Number (g) Number (h) Number Units Units Units Units Units Units Units Units

Explanation / Answer

a.
Req = (1010000/2 + 1010000) = 1515000 ohm
I1 = 3000/1515000 = 0.00198 A

b and c
V = 3000 - (0.00198*1010000) = 1000.2 V
I2 = I3 = 1000.2/1010000 = 9.9e-4

d. and e
R eq = 1010000 *2 = 2020000 ohm
I = 3000/2020000 = 0.001485 A

f. i =0 A

g. 1000.2 V

h. 0.001485 * 1010000 = 1499.85 V
