In this assignment, you will investigate the low-carbon technology that would be most suitable to provide heat and power for a domestic building.
• Using information try to identify the main energy demands associated with a domestic building (e.g. electricity for lighting and appliances, space heating, hot water etc.)
• With knowledge of the demands in your building investigate the technical characteristics of the below technology:
1. Engine-based combined heat and power, gas consumption.
The assignment hand-in should take the form of a short report in which you should: identify and justify the main building energy demands; describe the characteristics of the above technology, giving pros and cons (including costs) ;
Q. Show DC Generator Characteristics? Figure shows schematic diagrams of field-circuit connections for dc machines without including commutating pole or compensating windings.

AC Motors DC motors that have their magnetic fields produced by coils as described earlier can, in principle, be powered from AC as well, since if the applied voltage reverse
Q. Determine v, i, and the power delivered to elements in the network given in Figure. Check whether conservation of power is satisfied by the circuit.
1. The circuit below will be most efficiently analyzed by obtaining the Thevenin equivalent circuit for the circuit to the left of the points (a-b) on the schematic. The capacitor
Q. In an amplifier, the maximum voltage gain is 1500 and occurs at 1kHz. It falls to 1060.5 at 20kHz and at 20Hz. Determine (i) lower cut-off frequency (ii) upper cut-o
Q. Show Balanced three-phase loads? Three-phase loads can be connected in either wye (also known as star or Y) or delta (otherwise known as mesh or ). If the load impedances i
