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.
