RL Circuits

Q1:

If a 7.5 komega.gif resistance is connected to a 10 komega.gif inductive reactance in a series RL circuit, then the impedance equals 12.5 komega.gif .

A True

B False

ANS:A - True

Given , r=7.5k
xL=wL=10k
z=r+jxL => mod z =sq root of(r^2+xL^2)

impedance Z=sqrt[(7.5)^2+(10)^2]
=12.5
