16. In the given branch PQ of a circuit, electric currenti = (5t + 2) A is flowing, where t is time in second.At t = 1, the potential difference between pointsPand Q is10 VW 0000052H​

Answer»

Given:

i = (5T + 2) A

t =1

To FIND:

potential DIFFERENCE = V =?

Explanation:

The potential difference is the electric potential between two points.

This potential difference is given by

\displaystyle V = <klux>L</klux> \frac{dI}{dt}

where L is inductance in Henry & it constant.

∴\displaystyle V =L \frac{d}{dt}(5t +2)

  V = 5L V

So V is proportional to time.

∴ At t  = 1, V = 5L V
