Short circuit is occurred when:
Select one:
a. The voltage between the two terminals is zero although there may be a nonzero current
between the terminals.
b. All of the given answers.
c. There will be a zero-resistance connection between terminal A and B and therefore the 2
terminals are at the same voltage.
d. A pair of terminals connected by a wire (of zero resistance).

The resistance of each switch is negligible when closed. All of the connecting wires may be considered to have zero resistance. All of the resistors shown are identical. The circuit contains an ideal ammeter. The diagram shows all of the switches open. Beside the diagram are eight different switch configurations for the circuit. Rank these configurations in terms of the ammeter reading. That is, put first the configuration for which the ammeter gives the largest reading, and put last the configuration for which the ammeter gives the smallest reading. If two or more configurations produce the same ammeter reading, give these configurations equal ranking.
