A variable frequency ac source is connected to a capacitor. How will the displacement current change with decrease in frequency ?

A solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, will the current increase or decrease? Explain.

When ac source V = 220 sin (100 pi t) volt is connected to a parallel plate capacitor, displacement current is obtained maximum equal to 7600 mA. If diameter of plate of a capacitor is 36 cm then find perpendicular distance between the plates of this capacitor.
