How does capacitor behave to d.c.?

How does a semiconductor behave at 0K?

How does capacitive reactance X_c of a capacitor vary in an a.c. and d.c. circuit ?

At very high frequency of a.c. a capacitor behaves like conductor. Why?

How does a current loop behave like a magnetic dipole?

Explain how does capacity of parallel plate capacitor change on introducing a conducting slab?

For a given potential difference, does a capacitor store more or less charge with a dielectric than it does without a dielectric constant (K) is inserted between the two plates of capacitor. What is the new of charge stored in the capacitor?

What is solenoid? How does a solenoid behave like a bar magnet?
