Solution:
We know that at resonance the impedance of the circuit will be resistive only.
We will calculate the value of impedance in a complex form and equate its
imaginary part to zero to determine the value of R . Here, Z = R + j6 and Z 2
1
1
= 10 – j4
During resonance, the imaginary part of Z will be zero.
Therfore,
