Question

I=2A ф=40мВб L-? Помогите решить

Answer 1

Ф = LI
L = Ф/I = 0.04/2 = 0.02 Гн

Answer 2

Calculation of Inductance (L) Given Current (I) and Magnetic Flux (ф)

To calculate the inductance (L) given the current (I) and magnetic flux (ф), we need to use the formula:

L = ф / I

Where: - L is the inductance in henries (H) - ф is the magnetic flux in webers (Wb) - I is the current in amperes (A)

In your case, you have given that I = 2A and ф = 40mWb. Let's substitute these values into the formula to find the inductance (L):

L = 40mWb / 2A

To perform the calculation, we need to convert milliwebers (mWb) to webers (Wb). Since 1 milliweber is equal to 0.001 webers, we have:

L = (40 * 0.001) Wb / 2A

Simplifying the expression:

L = 0.04 Wb / 2A

Finally, we can calculate the value of L:

L = 0.02 H

Therefore, the inductance (L) is 0.02 henries (H) when the current (I) is 2 amperes (A) and the magnetic flux (ф) is 40 milliwebers (mWb).
