1. A motor draws 20A from 110V, 60HZ line with power factor of 77% lagging, calculate, (i) (ii) (iii) Active power absorbed by the motor Reactive power supplied by the line In-phase current component Quadrature current component Resistance of the motor (iv) (v) (vi) (vii) Impedance of the motor Reactance of the motor 2. If a 1000 uF capacitor is placed at the terminals of the motor in problem # 1 to reduce the amount of current, what will be the new value of line current and new PF of the motor? Assume that motor still requires same active and reactive power as being calculated in the last problem.

Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.
