In an A.C. circuit, a resistance of R Omega connected in series with an inductance If phase angle between voltage and current 45^@. Then what will be the value of inducti reactance ?

Answer»

`R/4`
`R/2`
R
cannot be FOUND with the GIVEN data.

Solution :`(omegaL)/R=tan 45^@`
`THEREFORE (omegaL)/R=1`
`therefore omegaL=R`
`therefore X_L=R`
