Question

In the circuit of the figure below, ℰ = 3.0 kV, C = 6.0 μF, R₁ = R₂ = R₃ = 0.72 MΩ. With C completely uncharged, switch S is suddenly closed (at t = 0).

(a) At t = 0, what is current i₁ in resistor 1?
A

(b) At t = 0, what is current i₂ in resistor 2?
A

(c) At t = 0, what is current i₃ in resistor 3?
A

(I got the stuff for the first part. but someone couldn't answer the next part without this part so here the first part so that you can get the information you need for part D-F)

Repeat for t = ∞ (that is, after many time constants.)

(d) What is current i₁?
___________A

(e) What is current i₂?
__________A

(f) What is current i₃?
__________A
