What is an open circuit
Wire that has rubbed into a power wire
A break in the wire
Wire that has rubbed into the ground
All of the above
Checking the circuit for continuity will always determine all electrical faults
true
false
The low-resistance fault causes abnormally high current flow in the circuit and may cause the circuit protection devices, such as fuses circuit breakers, to open the circuit
True
False
Alternating current
Moves from positive to negative
Moves from negative to positive
Moves back and fourth
Moves in one direction only

_____ is achieved when an electrical circuit has a continuous and uninterrupted connection and is thereby capable of conducting current and working as design
Continuity
Voltage drop
High resistance
Openness
Voltage can vary across different points in a circuit, but determining the current at any point can be done without an ammeter by using Ohms law.
True
