A 295 turn solenoid has a radius of 5.25 cm and a length of 23.5 cm. (a) Find the inductance of the solenoid. mH (b) Find the energy stored in it when the current in its windings is 0.501 A.

a)

b)

Explanation:

Given:

a)

The inductance of the solenoid is given as:

where:

permeability of the free space

cross sectional area of coil formed

b)

current in the coil,

The energy stored in the solenoid can be given as:

need to see circuit to get time constant

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
