Electrical current sensors measure AC and/or DC current levels.

Electrical power sensors are used to measure electric power

AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels

Voltage and current signal conditioners amplify or modulate AC or DC current or voltage and process signals to improve transmission

AC power cords carry alternating current from one area to another.

AC power connectors transfer alternating current through a variety of electronic devices.

Current transformers are used to step down current in a very predictable fashion with respect to current and phase.
