auxiliary anode वाक्य

उदाहरण वाक्य

1. The action of igniting the arc at a controlled time, each cycle, allows the ignitron to dispense with the auxiliary anode and control grids required by other mercury-arc valves.
2. In other types of mercury-arc valve, the arc is ignited just once when the valve is first energised, and thereafter remains permanently established, alternating between the main anode ( s ) and a low-power " auxiliary anode " or " keep-alive circuit ".
