Three identical bulbs each having power P are connected in series in an
electric circuit. In another circuit, another set of three bulbs of same power
are connected in parallel to the same source.
(i) Will the bulbs in both the circuits glow with the same brightness? Justify
your answer.
(ii) Now let one bulb in each circuit get fused. Will the rest of the bulbs
continue to glow in each circuit? Give reason.
(iii) Representing each bulb by a resistor, draw circuit diagram for each
case.
Or
Two coils C1 and C2 are wrapped around a non-conducting cylinder. Coil 1
is connected to a battery and key and 2 with galvanometer G. On pressing
the key (K), current starts flowing in the coil 1
. State your observation in
the galvanometer:
(i) When key K is pressed on
(ii) When current in the coil C1 is switched off.
(iii) When the current is passed continuously through coil C1
