\nTo assemble a household circuit comprising three bulbs, three (on\/off) switches,a fuse and a power source.<\/p>\n
\nApparatus:<\/strong> No apparatus required in assembling a circuit.
\nMaterial:<\/strong> Three bulbs (6 V, 1W) each, fuse of 0.6 A, main switch a power supply (battery . eliminator), three (on\/off) switches flexible connecting wire with red and black plastic covering,a fuse wire.
\nSupplementary:<\/strong>\u00a0Main electric board with a two-pin socket and main switch.<\/p>\n
\nElectricity supplied to us for domestic purposes is 220 V A.C. and 50 Hz. The household circuit, all appliances are connected in \u201cparallel\u201d with mains. The switches are connected in series with each appliances in live wire. 5 A switches are required for normal appliances like, bulbs, fluorescent tubes fans etc. 15 A sockets and switches are required for heavy load appliances ‘ like, refrigerator, air conditioner, geyser, hot plates etc. All appliances must have three wires called live, neutral and the earth. Total power consumption ‘P’ at a time
\nP = P1<\/sub> + P2<\/sub> + P3<\/sub> +………..
\nwhere P1<\/sub>, P2<\/sub>, P3<\/sub>\u00a0are the powers drawn by appliances.
\nTo protect the appliances from damage when unduly high currents are drawn fuse of \u00a0little higher rating, 10 to 20% higher than the current normally drawn by all appliances. For further safety, a suitable value MAINS FUSE like rating 32 A is connected in series with supply source.<\/p>\n
