Question

Оцените продолжительность искры возникшей (газового разряда), возникший при размыкании контура с катушкой индуктивностью 0,1 Гн, если известно, что искра в условиях опыта появляется при напряжении 10 кВ. Ток в контуре до размыкания был равен 2 А.

Answer 2

To calculate the duration of the spark that occurs when the circuit with an inductance coil of 0.1 H is opened, we need to use the formula for the energy stored in an inductor.

The energy stored in an inductor is given by the formula:

E = (1/2) * L * I^2

Where: - E is the energy stored in the inductor (in joules) - L is the inductance of the coil (in henries) - I is the current flowing through the circuit (in amperes)

In this case, the inductance (L) is given as 0.1 H and the current (I) before the circuit is opened is 2 A. We can calculate the energy stored in the inductor using these values.

E = (1/2) * 0.1 H * (2 A)^2

Simplifying the equation:

E = 0.1 J

The energy stored in the inductor is 0.1 joules.

Now, to calculate the duration of the spark, we need to know the power dissipated during the spark. Unfortunately, the power dissipated is not provided in the question. Without this information, it is not possible to determine the duration of the spark accurately.

If you have any additional information or if there is anything else I can help you with, please let me know.
