37.

Assertion (A): A quarter wave transformer is used to match a resistive load to a transmission line.

Reason (R): A quarter wave transformer is a transmission line of quarter wave length.

Both A and R are correct and R is correct explanation of A
Both A and R are correct but R is not correct explanation of A
A is correct but R is wrong
A is wrong but R is correct
Answer: Option
Explanation:

A line of length is called quarter wavelength line. Such a line is used for impedance matching.

If

A quarter wave line can match a source impedance Zin with load impedance ZL by selecting a proper value of Z0 so as to satisfy equation.

Such a line is also called transformer.
