Question

Энергия магнитного поля катушки с индуктивностью 0,6 Гн ровна 1,2 Дж. Чему равна сила тока в катушке?

Answer 1

W=(L*I^2)/2
I^2=2*W/L
I=√(2*W/L)=√(2*0,6Дж/1,2Гн)=1А

Answer 2

Calculating Current in the Coil with Given Inductance and Energy of the Magnetic Field

To calculate the current in the coil with an inductance of 0.6 H and energy of the magnetic field equal to 1.2 J, we can use the formula for the energy stored in an inductor:

Energy stored in an inductor (W) = (1/2) * L * I^2

Where: - W = Energy stored in the inductor (Joules) - L = Inductance of the coil (Henrys) - I = Current flowing through the coil (Amperes)

We can rearrange this formula to solve for the current (I):

Current (I) = sqrt((2 * W) / L)

Now, let's calculate the current using the given values:

Energy (W) = 1.2 J Inductance (L) = 0.6 H

Plugging these values into the formula:

Current (I) = sqrt((2 * 1.2) / 0.6) Current (I) = sqrt(4) Current (I) = 2 A

So, the current in the coil with an inductance of 0.6 H and energy of the magnetic field equal to 1.2 J is 2 Amperes.
