Answer 2

Answer:

( 5mj )

Explanation:

Given :-

R = 300  Ω

C = 20 MF = 20 ×10-⁶ f

Z = 500

To Find :-

the energy of magnetic field ?

$E = \frac{1}{2 } \: CV^{2} \\ = 21 \times {10}^{ - 3} j \\ = 25 \: mv \\ \\ MF \: energy \: = \frac{1}{2} \times 1 \times (0.1)^{2} \\ \\ = 5 \times 10 ^{ - 3} j \\ \\ \sf\underline{ \rm \red{5mj}}$
