Quiz sheet for complex circuits

If the series resistor became open circuit in a simple series-parallel circuit, the circuit current would:

A) drop to zero because of the break in the circuit current path.

B) be limited by the equivalent resistance of the parallel combination

C) decrease to the current taken by the parallel combination.

D) increase to the current taken by the parallel combination

ANSWER: A

If a short circuit occurs in a parallel branch of a group of series-parallel connected resistors the:
