... Table 2 shows the effect of further increasing R1 to reach the minimal power consumption achievable with the design approach in Fig. 4. Using R1 = 1 M reduces the total current consumption to 6.6 A at the cost of amplifying the noise in the circuit (due to the resistors and the op amp) by a higher ...

Alternating current
Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.AC is the form in which electric power is delivered to businesses and residences. The usual waveform of alternating current in most electric power circuits is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video).
