We define I to equal this constant intensity:

Nevertheless constant and superior intensity of German artillery destroyed communication trenches and prevented any movement.

Because of the symmetry, the lines of B flux must form circles of constant intensity centered on the axis of symmetry.

It is not absorbed by ozone and reaches the earth at a relatively constant intensity all year.

The overhead lighting was still furnished by the twin panel strips built in flush with the overhead, still with the same constant intensity.

Furthermore, no lamp has a constant intensity at all wavelengths.

In other words, it remains always at a constant intensity of the planetary gravitational force which means it keeps us at a nearly constant height above sea level.

Most tools vary the voltage at the main electrode in order to maintain a constant current intensity.

But when the light source was held at constant intensity, the amber filters, which generally let the most light through, had the best detection time.

A race, he said "is constant intensity, working just about every muscle in your body - neck, arms and forearms especially."
