In figure `i_(1) = 10 e^(-2t) A, i_(2) = 4 A, v_(C ) = 3 e^(-2t) V` The variation of potential difference acorss `A` and `C` with time can be represented asA. B. C. D. |
Answer» Correct Answer - B `V_(C ) - i_(2) R_(2) - i_(L) = V_(D) , V_(CD) = V_(C ) - V_(D) = i_(2) R_(2)+ i_(L)` Substitution the values we have, `V_(CD) = (4) (3) + 16 e^(-2t) , V_(CD) = (12 + 16 e^(-2t)) V` At `t = 0, V_(CD) = 28 V` , And at `t = oo, V_(CD) = 12 V` |
