It's possible to control the industry powerful constant circuit of commutating circuit through controlling the guide circuit Angle of controllable silicon by feedback pressure.

The light arrives at a low angle, however, as the Sun makes a daily circuit around the horizon, and icebergs cast long shadows over the surrounding sea ice.

The product of the effective values of the voltage and current with the cosine of the phase Angle between current and voltage in an alternating-current circuit.
