we often say "a current is going through the wire " What goes through the wire,the charge or the current ?

If 0.6 mol of electorns flows throutgh a wire in 45 min, what are (a) the total charges that passes through the wire and (b) the magnitude of the current?

If a direct current of value a ampere is superimposed on an alternative current I=b sin omega t flowing through a wire, what is the effective value of the resulting current in the circuit?

A long straight current carrying wire passes normally through the centre of circular loop. If the current through the wire increases, will there be an induced emf in the loop ? Justify.

Displacement current goes through the gap between the plates of a capacitor when the charge of the capacitor

(A) : A loosely wound helix made of stiff wire is suspended vertically with the lower end just touching a dish of mercury. When a current is passed through the wire, the helical wire, the helical wire executes oscillatory motion with the lower end jumping out of and into the mercury. (R) : Like current carrying wires attract each other.

If a direct current of value a ampere is superimposed on an alternating current 1 = b sin omega t flowing through a wire, what is the effective value of the resulting current in the circuit?

A negative test charge is moving mear a long straight wire carrying a current. The force acting on the test charge is parallel to the direction of the current. The motion of the charge is:

The plot represents the flow of current through a wire at three different times. The ratio of charges flowing through the wire at diffferent times is
