A choke coil is needed to oprated an arc lamp at 160V(rms)and 50Hz. The arc lamp has an effective resistance of `5 Omega` when running of 10A(rms). Calculate the inductance of the choke coil. If the same arc lamp is to be operated on 160V(dc), what additional resistnce is requried? Compare the power losses in both the cases.
