A direct current of 5A flow through a 0.2H inductor. Calculate the energy stored in the inductor
0.5J
1.0J
2.5J
5.0J
Correct answer is C
P = \(\frac{1}{2} I^2 L\)
= 5\(^2 \times\) 0.2 \(\times\) \(\frac{1}{2}\)
= 2.5J
5
12
2000
2400
Correct answer is A
\(\frac{E_s}{E_p} = \frac{N_s}{N_p} = \frac{240}{12} \frac{100}{N_p}\)
Np = 5
