Questions
An inductive coil has a resistance of 100 ohms. When an ac signal of frequency 1000 Hz is fed to the coil, the applied voltage leads the current by . What is the inductance of the coil?
detailed solution
Correct option is C
here ϕ =450 and ω=2000π and R =100 ohms tanϕ= LωR Therefore L= Rω=1002000×3.14H =16 mHTalk to our academic expert!
