FR 14B - 250.30 Path of Least Resistance

In electrical circuits, how does current flow in relation to resistances?

Current flows through all available conductive paths, proportionately to the resistance of each path.

Current does not flow through any resistances, only around them.

Current ignores all resistances and spreads evenly across all paths.

Current flows only through the path of least resistance.

What is the purpose of using a megger in electrical testing?

To test for insulation breakdown or leakage at high voltages.

To determine the conductivity of a conductor.

To check the capacity of a battery in a circuit.

To measure the color of the insulation on wires.

Why is it advised to work with one hand in your pocket while dealing with electrical circuits?

To reduce the risk of current passing through the chest by providing a path from one hand to the other.

To improve balance and prevent falling onto electrical equipment.

To ensure one hand is always free to take notes.

To prevent carrying tools that might cause a short circuit.
