DC Theory Lesson 3
What type of circuit has no current flow through it?
Open
A(n) ? circuit allows current to flow to the intended destination through the load and back to the source.
Complete
Frequent problems in electrical systems are from ? .
Connection points and switching systems
How is a switch rated?
Max current max voltage
A ? is a set of contacts that move when a signal is transferred to the operating electromagnet.
Relay
A circuit that is drawn on paper and depicts a systematic way that current will flow is referred to as a(n) ? diagram.
Schematic
The term ? comes from the fact that the current has taken a shorter path back to the source, avoiding the opposition of the load.
Short circuit
A switch that either makes or breaks one circuit path at a time is referred to as a ? switch.
Single Pole
A ? is a mechanical device designed to allow or interrupt current flow in a circuit.
Switch
Two ? switches are used to control a light load from two locations.
Three-way
The number of actions that allow us to close a switch is referred to as the ___?___ of the switch.
