All our transmission is done at high voltage direct current.
Electrical power is supplied to single-trolley railroads principally in the form of direct current.
How does a conductor behave in connection with direct current and how with alternating current?
The presence of the condenser precludes the possibility of direct current flowing in this path.
The switches of the direct current circuits are hand-operated and are located upon boards at the right and left of the control board.
