The dispersion relation for parallel propagating whistler wave in an electromagneto plasma for both parallel and transverse orientation of a dc electric field has been derived. The electric field induced cyclotron instability has been studied for a wide range of parameters to show the relative importance of electric field strength, temperature anisotropy, parallel thermal velocity, and the ratio of particle pressure to magnetic pressure. It is found that the wave grows (or damps) in amplitude for a parallel for antiparallel) electric field. In the case of the transverse dc electric field, the magnitude of growth rate and the width of the region of wave amplification in frequency domain increases with increasing temperature anisotropy. The contribution of the transverse electric field towards the wave growth is negligibly small as compared to temperature anisotropy.
