AN EQUIVALENT-CIRCUIT REPRESENTATION OF ALFVEN WAVES

Equivalent electric circuit elements of Alfven waves in solar coronal holes of different temperatures and magnetic field strengths have been studied. In an L-R circuit the resistance is found to increase with m agnetic field strength but shows no temperature dependence whereas ind uctance decreases with magnetic field strength but increases with temp erature. As a consequence of this the damping time of L-R circuit decr eases with magnetic field but increases with temperature. The purely r esistive load impedance of Alfven waves increases with height in the c oronal hole. In case of equivalent transmission line the resistance an d inductance increase with temperature but show no magnetic field depe ndence, whereas capacitance increases with temperature but decreases w ith the magnetic field strength.
