Question

an unplanned open may cause higher than normal current flow. a) true b) false

Explanation:

An open circuit means there is a break in the circuit path. According to Ohm's law \(I = \frac{V}{R}\), when there is an open (infinite resistance in the open - part of the circuit), the current \(I\) will be \(0\) (assuming a finite voltage source). A higher - than - normal current flow is typically caused by a short circuit (low resistance path), not an open circuit.

Answer:

B. False
