Consider the following statement. A1: I = 0 A2: I=(V/R)(e -1/(RC) ) B1: V c = 0

Question

Consider the following statement. A1: I = 0 A2: I=(V/R)(e-1/(RC) ) B1: Vc = 0 B2: Vc = V B3: Vc = Ve-1/(RC)
After a very long time, the current through R and thepotential across the capacitor are given respectively by 1) A3, B3 2) A3, B1 3) A2, B1 4) A1, B2 5) A3, B2 6) A1, B3 7) A1, B1 8) A2, B3 9) A2, B2 Consider the following statement. A1: I = 0 A2: I=(V/R)(e^-1/(RC) ) B1: Vc = 0 B2: Vc = V B3: Vc = Ve^-1/(RC) After a very long time, the current through R and thepotential across the capacitor are given respectively by 1) A3, B3 2) A3, B1 3) A2, B1 4) A1, B2 5) A3, B2 6) A1, B3 7) A1, B1 8) A2, B3 9) A2, B2

Explanation / Answer

after a long time, the capacitor is charged so the current iszero. At this time the potential across the cap is equal to thepotential of the battery. So the answers are   I =0   and Vc = V . Which are   A1 and B2    So theanswer is   4) A1, B2
