358384 Assertion :
The quantity \(L/R\) possesses dimension of time.
Reason :
To reduce the rate of growth of current through a solenoid, we should increase the time constant \((L/R).\)

358385 A 30 Henry inductor coil is connected to a \(20 \,\Omega\) resistance in series (as shown in figure). The time at which rate of dissipation of energy (Joule's heat) across resistance is equal to the rate at which magnetic energy is stored in the inductor, is
[Take \(l\)\(n2 = 0.69\)]

358386 An ideal coil of \(10\,H\) is connected in series with a resistance of \(5\,\Omega \) and a battery of \(5\,V\). After \(2\,s\), after the connection is made, the current flowing (in ampere) in the circuit is

358387 Assertion :
The growth of current in R-L circuit is uniform.
Reason :
Inductor \((L)\) opposes the growth of current.
