The correct answer is a. All parts of the circuit will begin to carry a greater amount of current than normal.Explanation:When two or more than two conductors of different phases touch each other in a power line, the part of the impedance is switched out of the circuit due to a large current flow in the un phase failure, current is called the short circuit current. The short circuit current decreases the impedance of the circuit, while the current in the circuit increases.
