Answer / p,btech student , e&e engg
Resistance of bulb
1(R=(V)^2/P)
=(110)^2/100 =121
ohm
resistance of blb 2
=(230)^2/200=264.5
ohm
so voltag drop
across bulb 2 will
be more (series
connection) .So
when connected in
series ,bulb 2 will
glow brighter.
| Is This Answer Correct ? | 2 Yes | 0 No |
bulb 1 required 0.909 Ampere,
bulb 2 required 0.869 Ampere to full glow.
If we connect both in series.
same current will flow in both bulbs
bulb 2 required low current then bulb 1, so bulb 2 will
flow beter.

Answer / baskaran
first this question is not clear, because input voltage not
given this circuit.
ok
if input voltage 230 volts.
in series circuit Vt = Vr1 + Vr2
so each load gets 110 vols
so bulb 1 (110v,100w) glow brighter..

In power transmission using open belts or horizontal shafts it is preferable to have the slack side of the belt on the top because
after parallaing two generators current is shooting up in both the generators.for ex: load is 400 kw..after paralling and load sharing current in running gen is approx 900 amps and incoming is 750 amps which is too high when trying toshift the load current in incoming gen is coming more than 1300 amps and both getting tripped and making blackout..
