The magnitude of both scalar and vector quantities are represented by the ? of a line.

Length

When current flows in a conductor, a magnetic field is produced. As free electrons move in one direction, their individual magnetic fields

?.

Add together

Counter Electromotive Force is sometimes called back EMF, and CEMF is? out-of-phase with the applied voltage.

180 degrees

Vectors can be __ using the parallelogram method

Added

Skin effect increases the effective resistance of the conductor.

True

At what degrees on the sine wave is the voltage equal to zero?

0, 180, 360

When a conductor cuts the magnetic flux lines at ?, the maximum voltage will be induced into the conductor.

A(n)? occurs each time the AC generator finishes one complete rotation (360° travel).

Cycle

The ? is the value of AC voltage that produces the same amount of power as a like value of DC voltage.

The RMS value

Power in a circuit is the amount of work done per unit of ?.

Time
