Sam visited his uncle’s house who is an electrician . He saw resistors and few
electrical equipments like ammeter , voltmeter , key and battery on his work table.
His scientific curiosity increased and started connecting three resistors of equal
resistances in series and then in parallel. His interest landed on 250 W television
used for one hour , 1200 W toaster used for 10 minutes . He then came to a
conclusion and understood which device used more energy . Answer any four
questions. (4m)
(a) Draw circuit diagrams for series and parallel combination .
(b) If three resistors of resistance R are first connected in series and then parallel .
Find the ratio of their resistances
(c)
V
I
What type of combinations do the linear curves represent . Justify your statement
(d) If 250 W television used for one hour , 1200 W toaster used for 10 minutes ,
which device used more energy ?
(or)
How many bulbs of 8Ω should be joined in parallel to draw a current of 2A from
battery of 4V .
(e) List the advantages of parallel connection .

Answer:
I always love to go at uncle sam's house. but everytime i noticed something miracle in his son, niel. i noticed for the first time his power of prediction. at that time he predicted everything. whenever we watched movie he predicted very well the future movie and it was strange because he does that for each and every time. it was the strange thing i noticed in him and then after i asked him about his predictions so he nod his had and passed an evil smile on me. i was most scared then. and for the next time i went their with the excitement to know him mire. i told him to come with me and i just locked him in a room.And i ran from there. when i went in my uncle's room he was sitting on the couch and passing the same smile at me. i stared him with the odd reflection. he got up came close at me and said "dont try to identify me". i cried and ran away. after i told my uncle about him but he refused to listen to me. it was most dangeroust moment for me when he came closer to me and said those words.
