An LR Series Circuit has an inductor of inductance L, connected in series with a resistor of resistance R. The resistance is the DC resistive value of the wire loops or turns which goes into making up the inductors to the coil.
We know that AC
irms = 0.2 – Vrms/z = 12/z
Or
z = 12/0.2 = 60 ohm
For DC
i = 0.4 = V/R = 12/R
So we get
R = 12/0.4 = 120/4 = 30 ohm
As there is current in a steady state of the DC circuit, there is no capacitor
z > R
So the second component other than the resistor is the inductor.
The circuit will be series LR.
Therefore, the circuit is series LR.
Summary:
Circuit when connected to the AC source 12 volts gives the current of 0.2 ampere same circuit when connected to the DC source 12 v, gives a current of.0.4 A,m. the circuit is (A) series LR (B) series RC (C) series LC (D) series LCR
Circuit when connected to an AC source 12 volts gives the current of 0.2 amperes, the same current when connected to the DC source 12 v, gives a current of.0.4 A,m. The circuit is series LR.
