PhysicsEasysingle choice

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

Options:

Answer:

Solution:

Time constant is $L / R$ Given, $L = 40 H & R = 8Ω$ $∴ τ = 40/8 = 5 sec$ .
