Define the term passive reference configuration. When do we have this configuration when using double subscript notation?

a. Description of lamp-ballast system b. Choose the power rating of T8 fluorescent lamp to be used in the system c. The operation of lamp-ballast circuit d. The modelling of the lamp-ballast by an equivalent circuit e. The design of inductance of the choke of the lamp-ballast system f. Determine the supply current and power factor g. Decide the desire power factor to be achieved and state the reason for the chosen of that value of power factor h. The design of size of capacitor for power factor correction. i. Team members information

3. i. Write the working principle of Permanent Magnet Moving Coil instrument mention the importance spring used. ii. Explain how a single PMMC instrument can be used as ammeter and voltmeter.

With the aid of well labeled diagrams, explain the principle of operation of: a. a pyranometer. b. a wind turbine, from resource to electrical power

Interpret the circuit by answering the guide questions, this is a simple power supply with full-wave bridge type rectifier. Define the following: ac source, fuse, SPST switch, transformer, full- wave rectifier, capacitor as a filter, load (resistive load). b. How does this power supply circuit work? а. FULL-WAVE BRIDE RECTIFIER TRANSFORMER ON/OFF SWITCH FUSE FILTER DC OUTPUT VOLTAGE AC LOAD SOURCE

Figure 1 shows the circuit diagram for a simple d.c. power supply. a. Identify the type of rectifier circuit represented in figure 1 and explain the operation of the circuit with reference to the function of each component within the circuit. b. Sketch to scale the voltage across R as a function of time showing its relationship to the secondary voltage from the transformer.

1- Draw the complete circuit diagram that illustrates the experiment concept as in figure 5 by showing the pins number. Show the following in your plot (Arduino board, steppermotor coils and the driver circuit). Note: The drawing should be on paper and not with artificial intelligence, please.

With the use of suitable diagrams as appropriate, explain how a typical wind electrical generator and a solar energy system are controlled using the relevant power electronic converters. Your explanation should include a description of all steps of power conversion and how this is used to maintain a constant output supply Wind electrical generator controlled using power electric converters.   Solar energy systems controlled using power electric converters.

Define slew rate with the formula and its unit.
