Inductance

Explanation of question 8

A coil has an inductance of 200mH and a resistance of 4. When connected across a 12 V DC supply, the final current will be

  1. 0.06mA
  2. 600mA
  3. 3A
  4. 60A

The answer is :- 3 Final current depends only on the resistance. The effect of the inductance is only to delay this value of current being reached.
