Acoil is connected in series with a 8.41 kω resistor. an ideal 68.6 v battery is applied across the two devices, and the current reaches a value of 1.64 ma after 6.26 ms. (a) find the inductance of the coil. (b) how much energy is stored in the coil at this same moment?

The inductance and stored energy are 234 H and

Explanation:

Given that,

Resistance R= 8.41 kΩ

Voltage V= 68.6 V

Current I = 1.64 mA

Time t = 6.26 ms

We need to calculate the maximum current of the coil

Using formula of maximum current

We need to calculate the inductance of the coil

(b). We need to calculate the stored energy

Using formula of stored energy

Hence, The inductance and stored energy are 234 H and

thermal energy is the answer
