DigE Ch05 Basic Electrical Circuit Materials

Front

What does insulation color coding assist in?

Back

Tracing the conductor, representing voltage and polarities, representing grounding conductors, and all of the above.

Front

True or False: All of electricity and electronics is based on the fundamental concept of moving electrons through a material and then applying the electrons to a load.

Back

True

Front

What is electrical pressure loss across a length of conductor called?

Back

Voltage drop.

Front

How many inches is a mil equal to?

Back

0.001 inch.

Front

Conductors with a large diameter can carry what compared to small-diameter conductors of the same material?

Back

More current than.

Front

Define 'voltage drop'.

Back

The reduction in voltage in an electrical circuit between the source and the load.

Front

What is the unit of electrical resistance?

Back

Ohm.

Front

What is the relationship between current, voltage, and resistance in a circuit?

Back

Ohm's Law: V = I × R (Voltage = Current × Resistance).

Front

What is the purpose of grounding in electrical circuits?

Back

To provide a safe path for excess electricity to flow into the ground, preventing electric shock and equipment damage.

Front

What is a conductor?

Back

A material that allows the flow of electric current, typically metals like copper and aluminum.
