The current whose magnitude changes with time and direction reverses peridically is called direct current. (True/False)

Name some sources of direct current.

The electric current has both magnitude and direction and hence a vector quantity. (True/False)

Two long conductors, separated by a distance d carry current I_(1) and I_(2) in the same direction . They exert a force F on each other. Now the current in one of them is increased to two times and its direction is reversed . The distance is also increased to 3d. The new value of the force between them is

Lenz's law cannot be used to find the direction of induced current. (True/False)

Displacement current is due to time rate of change of electric flux in some part of electric current. (True/False)

What is the frequency of direct current?

Which of the following is source of direct current?

The current flows form A and B as shown in the figure. The direction of the indueced current in the loop is
