Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt (one joule per second). Use this tag where power is a primary concern for the design under discussion. Use the "low-power" tag when that applies.

Convert DC generator to variable AC

Is there a way to convert a DC generator signal to AC and be able to control the frequency and current? Ultimately, I would like to use this signal to measure the impedance of a battery.
