How do we know which relay contact is actuated by which relay coil? How does this convention
differ from that of standard electrical/electronic schematic diagrams, where the relay coil is
shown as an actual coil of wire (inductor symbol) with the contact "linked" to the coil by a
dashed line? Also, what type of logic function behavior (AND, OR, NAND, or NOR) does the
above circuit exhibit?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5594cdc3-92d0-4164-bd05-7c4261092ce4%2F32f2a65e-b311-48cf-b14b-4da136fd4cad%2Fz3wgkz_processed.jpeg&w=3840&q=75)
