students‚ with second grade being the primary use case. By using the book "Cry-baby Moon" this science lesson will help teach students learn about objects in the sky‚ rainstorms‚ and phases of the moon. Lesson Plan Objectives After this lesson‚ students will be able to better distinguish between different phases of the moon Children will learn about other objects in the sky‚ such as the clouds Students will learn about what happens during a rain storm (Clouds-Rain-Lightning/Thunder-Rainbow)

3 Three-Phase A.C. Circuits Learning Outcomes This chapter introduces the concepts and principles of the three-phase electrical supply‚ and the corresponding circuits. On completion you should be able to: 1 Describe the reasons for‚ and the generation of the three-phase supply. 2 Distinguish between star (3 and 4-wire) and delta connections. 3 State the relative advantages of three-phase systems compared with single-phase-systems. 4 Solve three-phase circuits in terms of phase and line quantities

Tracking(locked) ABSTRACT We were assigned to build a phase locked loop frequency synthesiser. The purpose is to help students to gain experience in hardware construction‚ coordinated teamwork and project management. The design uses 74HC4046‚ a PLL integrated circuit (IC) made from CMOS technology A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal. The term “lock” refers to a constant or zero phase difference between two signals. The signal from

1 A Voltage-Controlled Oscillator (VCO) is a circuit that provides a varying output signal (typically of square-wave or triangular-wave form) whose frequency can be adjusted over a range controlled by a dc voltage. An example of a VCO is the 566 IC unit‚ which contains circuitry to generate both squarewave and triangular-wave signals whose frequency is set by an external resistor and capacitor and then varied by an applied dc voltage. Figure (1) shows that the 566 contains current sources to charge
