Chapter 27.4, Problem 27.5QQ

Consider the circuit in Figure 27.17 and assume the battery has no internal resistance. (i) Just after the switch is closed, what is the current in the battery? (a) 0 (b) ε/2R (c) 2ε/R (d) ε/R (e) impossible to determine (ii) After a very long time, what is the current in the batten? Choose from the same choices.

Figure 27.17 (Quick Quiz 27.5) How does the current vary after the switch is closed?

Can you help me solve a simple circuit. I'm having trouble finding the current and voltage drop across each resistor
this is one of my worksheet questions, it is physics, I got the answer 0.016 but I'm not sure.
4. (a) In the figure the current in resistance 6 is i6 = 1.38 A and the resistances are R1 = R2 = R3 = 1.54 N, R4 = 17.7 N, R5 = 8.42 N, and R6 = 4.95 N. What is the emf of the ideal battery? 5. R R Rg R4 (b) In A certain parallel-plate capacitor is filled with a dielectric for which K = 6.24. The area of each plate is 67400 mm2, and the plates are separated by 1.85 mm. The capacitor will fail (short out and burn up) if the electric field between the plates exceeds 172 kN/C. What is the maximum energy that can be stored in the capacitor?
