Answer 1

OPTION D

Explanation:

It is given that the current in the circuit is given by V divided by the sum of t and T.

Denoting this mathematically we would have:

`$ J = (V)/((t + T)) $`

Now to solve for T rewrite the above expression.

`$ J = (V)/((t + T)) \implies t + T = (V)/(J) $`

⇒ T =
`$ (V)/(J) $` - t

Therefore the answer would be Option D.
