. The power loss in the circuit is
Text Solution
Verified by ExpertsThe correct answer is:
C
Given, inductance, 
Capacitance, 
Resistance, 
and emf, 
… (i)
The general equation of emf is given as 
… (ii)
On comparing Eqs. (i) and (ii), we get
The power loss associated with the given AC circuit is given as
P 
R … (iii)
Substituting the given values in the above equation, we get
Z 
Now, substituting this values in Eq. (iii), we get
Thus, the power loss in the circuit is 0.79 W.
