Question

Электрический ток в проводнике с напряжением на концах 3 В за 3 сек совершает работу 18 Дж.Чему равна сила тока в проводнике?

Answer 1

По закону Джоуля-Ленца.
Q=UIt
Q=A
A=UIt
I=A/Ut
I=18/9
I=2A

Answer 2

Calculation of Electric Current

To calculate the electric current in a conductor, we can use the formula:

Electric Current (I) = Work Done (W) / Time (t)

In this case, the work done (W) is given as 18 J and the time (t) is given as 3 s. Plugging these values into the formula, we can calculate the electric current:

I = 18 J / 3 s = 6 A

Therefore, the electric current in the conductor is 6 A.
