Answer 1

Answer:

OPTION D

Step-by-step 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:

                              $J = \frac{V}{(t + T)}$

Now to solve for T rewrite the above expression.

$J = \frac{V}{(t + T)} \implies t + T = \frac{V}{J}$

⇒                          T = $\frac{V}{J}$ - t

Therefore the answer would be Option D.
