The conductors 3.4 on both sides are also cooled by passing cooling water into a hollow pipe 5 which is integrally fixed thereto. As shown in FIG. 2, the electric circuit is used when power at two different frequencies f1 and f2 is simultaneously applied from one power source 8 to a load 6.7 consisting of two coils etc. connected in series, and the common conductor 1 is the connection point 9 between loads 6 and 7
Also, the conductors 3.4 on both sides are connected via capacitors 10.11 to the opposite ends of the load 6.7 from the connection point 9, respectively.
