Question

4) 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 ?
