Two inductors are placed in a circuit in series with each other. Inductor 1 has an inductance of 3.5e-3 H and inductor 2 has an inductance of 1.38e-4 H. Anytime current is running through the inductors, what is the ratio of energy stored in inductor 1 compared to inductor 2? U1 is the energy in inductor 1 and U2 is the energy in inductor 2.

Respuesta :

Answer:

Ratio of energy stored in the inductor will be 2.536

Explanation:

We have given two inductance [tex]L_1=3.5\times 10^{-3}H[/tex]

[tex]L_2=1.38\times 10^{-4}H[/tex]

As inductors  are connected in series so current will be same in both inductor

Energy stored in inductor is equal to [tex]\frac{1}{2}Li^2[/tex]

[tex]U_1=\frac{1}{2}\times 3.5\times 10^{-3}\times i^2......EQN 1[/tex]

Energy stored in second inductor

[tex]U_2=\frac{1}{2}\times 1.38\times 10^{-4}\times i^2......EQN 2[/tex]

Dividing equation 1 by equation 2

[tex]\frac{U_1}{U_2}=\frac{\frac{1}{2}\times 3.5\times 10^{-3}i^2}{\frac{1}{2}\times 1.38\times 10^{-4}i^2}=2.536[/tex]
