SITUATION
The current path for transmission from west to east on a full-duplex teletypewriter circuit is shown in figure 86.
Each circuit component is given an identifying number in this situation. Trace the current path through the circuit, using
the list of numbers below.
1.
The line.
2.
Ground at east.
3.
The transmitting contacts.
4.
The selector magnet at east.
5.
Ground near the battery at west.
6.
The positive side of the battery.
7.
The current adjust potentiometer.
Exercise 15 is based on this situation.
15.
The current flows through the circuit in sequence through:
a.
1, 4, 6, 3, 2, 5, 7.
b.
4, 5, 1, 3, 2, 7, 6.
c.
7, 6, 2, 4, 5, 1, 3.
d.
3, 7, 1, 4, 2, 5, 6.
16.
The two windings around the armature of a polar relay are called the:
a.
bias winding and the line winding.
b.
send winding and the receive winding.
c.
polar winding and the neutral winding.
d.
current adjust winding and the voltage adjust winding.
