A8.3-v battery is connected in series with a 43-mh inductor, a 180-ω resistor, and an open switch. what is the current in the circuit 0.120 ms after the switch is closed? how much energy is stored in the inductor at this time?

18.26 mA

Explanation:

We have given voltage V = 8.3 Volt

Resistance R=180 ohm

Inductance L=43 mH

Time at which we have to find the current t=0.120 ms

The current in the RL circuit is given by here is time constant which is given by

So the current

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
