Question

In an L-C-R circuit, 100 volt alternating voltage is applied between end points. In circuit inductive reactanve is XL -20 ohm, capacitance reactanve is XC-20 ohm and resistance is of 5ohm. The impedance of circuit eill be​

Answer 1

Answer:5 ohm

Explanation:

impedance is= [R^2 +(XL^2 -XC^2)] ^1/2

therefore impedance here is= [5^2+(20^2-20^2)]^1/2

=25^1/2=5ohm
