Explain why the e.m.f. generated in a conductor of an alternating-current generator is seldom sinusoidal. A rectangular coil of 55 turns, carried by a spindle placed at right angles to a magnetic field of uniform density, is rotated at a constant speed. The mean area per turn is 300 cm2. Calculate: (a) the speed in […]

A half-wave rectifier circuit is used to charge a battery of e.m.f. 12 V and negligible internal resistance. The sinusoidally varying alternating supply voltage is 24 V peak. Determine the value of resistance to be connected in series with the battery to limit the charging current to 1.0 A. What peak current would flow in […]

A full-wave rectifier circuit supplies a 2000 Ω resistive load. The characteristics of the diodes used can be considered ideal and each half of the secondary winding of the transformer develops an output voltage of 230 V. If the mean current in the load is to be limited to 100 mA by the connection of […]

A 50 kVA single-phase transformer has a turns ratio of 300/20. The primary winding is connected to a 2200 V, 50 Hz supply. Calculate: (a) the secondary voltage on no load; (b) the approximate values of the primary and secondary currents on full load; (c) the maximum value of the flux.

 We have a 3.333kW motor with a mass of 506kg. The casing of motor can be approximated to a cylinder with length 100cm and 70cm diameter. The motor is 75% efficient. Given the specific heat of motor 700 J/kg°C. Also we know that the surface of motor is capable of dissipating 12.5 W/m2 oC. of […]

I am developing a smart irrigation system and I need to come up with a system test plan. A template from online could be used but it needs to be tailored to my project specifically. The components in my system include: Water tank, water pump, water hose, Dht11 sensor, relay, arduino uno, LCD display screen, […]

 Answer the following questions: ·  What standards were used in your design?  How did the standards impact your design? ·  What are some of the societal, global, legal, ethical, and environmental impacts associated with your product?  This needs to be a specific and well-thought out response as it will be placed in the final report you […]

  What engineering standards are used in a smart water irrigation system?  How did the standards impact your own water irrigation system?   What are some of the societal, global, legal, ethical, and environmental impacts associated with your water irrigation system?  This needs to be a specific and well-thought out response as it will be placed in the […]
