Use "circuit" in a sentence
  • "The circuit containing the battery, transmitter, and primary winding of the induction coil is called the _local circuit_."
  • "The circuit of a complete pair of cords and plugs with their associated apparatus is called a _cord circuit_."
  • "The advantages of putting the transmitter and the battery which supplies it with current in a local circuit with the primary of an induction coil, and placing the secondary of the induction coil in the line, have already been pointed out but may be briefly summarized as follows: When the transmitter is placed directly in the _line circuit_ and the line is of considerable length, the current which passes through the transmitter is necessarily rather small unless a battery of high potential is used; and, furthermore, the total change in resistance which the transmitter is capable of producing is but a small proportion of the total resistance of the line, and, therefore, the current changes produced by the transmitter are relatively small."
