DC Motors: The Basics – ITP Physical Computing

WebDC power can be defined simply Pdc = Udc × Idc where U is DC voltage and Idc is DC current. As the inverter basically converts DC power to AC power and vice versa, the Pac and Pdc have to be equal (minus the losses, which are now omitted for simplicity). The DC power formula shows that by lowering the DC voltage, the DC current will be higher. WebDirect current (DC) is one-directional flow of electric charge.
