Question

An advantage of parallel circuits is that they A) stop transmitting all current if even one resistor breaks. B) form a single path through which the current flows. C) allow current to flow even if some paths are cut. D) divide the voltage evenly between all resistors.

Answer 1

Answer: C) allow current to flow even if some paths are cut.

Explanation:

In parallel circuit, the components are arranged in parallel paths across the same potential difference. The overall resistance decreases in parallel circuit. Different amount of current flows in different paths according to the resistance offered by the components. The main advantage of the parallel circuit is even if one component fuses, it does not effect other components. Thus, the current flows in the other paths even if one path disconnects.

Answer 2

Parallel circuits allow current to flow even if some paths are cut, because a parallel circuit has more than one current-carrying path through it.
