A coil of 40 henry inductance is connected in series with a resistance of 8ohm8 \mathrm{ohm} and the combination is joined to the terminals of a 2 volt battery. The time constant of the circuit is:

Options

  1. A5 seconds
  2. B1/5 seconds
  3. C40 seconds
  4. D20 seconds

Correct answer

A. 5 seconds

Step-by-step solution

According to the question Time constant LRL R circuit is T=LPT=\frac{L}{P} \therefore \quad T=5 sec\mathrm{sec}
