Answer: A,C,D,E are correct statements of an inductor
A. When an inductor and a resistor are connected in series with a DC battery, the current in the circuit is reduced to zero in one time constant.
C. An inductor always resists any change in the current through it.
D. When it is connected in a circuit, an inductor always resists having current flow through it.
E. Inductors store energy by building up charge.
Answer:
Induced emf will be 0.468 volt
Explanation:
We have given diameter of wire d = 15.3 cm
So radius 
So area 
Change in magnetic field dB = 0.26 - 0.77 = -0.51 T
Time for change in magnetic field dt = 0.26 sec
We know that emf is given by

Answer:A- mass charge.
This can also be called current.
Explanation:
This is Kirchhoff’s 2nd law.
Kirchhoff’s junction law states that the sum of current(mass charge) flowing in and out of the junction must be equal to zero. This law emphasizes conservation of charge and energy. Charge is also a form of energy and it can neither be created nor destroyed.
I think it's B hope it helps
