Questions based on L.R. Circuit | Growth and decay of current In L-R Circuit

In an LR circuit, R = 100 Omega and L = 2 H . If an alternating voltage of 120 V and 60 Hz is connected in this circuit, then the value of current flowing in it will be ______ A nearly

Consider a circuit consists of resistors, inductor, battery and a switch as shown. Resistance of resistors, inductance of inductor and EMF of battery are indicated. The switch is closed at t=0 . Find time constant of LR circuit during growth of current

Assertion: An inductance and a resistance are connected in series with an AC circuit. In this circuit the current and the potential difference across the resistance lag behind potential difference across the inductance by an angle pi//2 . Reason: In LR circuit voltage leads the current by phase angle which depends on the value of inductance and resistance both.

The dimensionsof "time constant" L/R during growth and decay of current in all inductive circuit is same as that of

Show that the sum of instantaneous currents during growth and decay of current in LR circuit is independent of time.

When a capacitor is connected in series with series LR circuit, the alternating current in the circuit increases. Why ?
