152698 When three identical bulbs of $60 \mathrm{~W}, 200 \mathrm{~V}$ rating are connected in series to a $200 \mathrm{~V}$ supply, the power drawn by them will be

1 $60 \mathrm{~W}$
2 $180 \mathrm{~W}$
3 $10 \mathrm{~W}$
4 $20 \mathrm{~W}$
Current Electricity

152699 Two $220 \mathrm{~V}, 100 \mathrm{Wbulbs}$ are connected first in series and then in parallel. Each time the combination is connected to a $220 \mathrm{~V}$ AC supply line. The power drawn by the combination in each case respectively will be

1 $200 \mathrm{~W}, 150 \mathrm{~W}$
2 $50 \mathrm{~W}, 200 \mathrm{~W}$
3 $50 \mathrm{~W}, 100 \mathrm{~W}$
4 $100 \mathrm{~W}, 50 \mathrm{~W}$

152700 An electric kettle has two heating coils. When one of the coils is connected to an AC source, the water in the kettle boils in $10 \mathrm{~min}$. When the other coil is used the water boils in $\mathbf{4 0}$ min. If both the coils are connected in parallel, the time taken by the same quantity of water to boil will be

1 $25 \mathrm{~min}$
2 $15 \mathrm{~min}$
3 $8 \mathrm{~min}$
4 4 min
