Answer / pradyumna chandra panda
by replacing 100w bulb the total resistance is decreased then the current flow the circvit will increase
therefore the heater giue more heat.

Answer / rahul kumar
We. Know
P=vi then as connection is in series then current will remain same so when instead of 60 watt if 100 watt bulb is used then it's voltage will increase...now we know v=iR then since current is same due to series connection so our resistance will increase and as resistance increases heater output will get increased......

Answer / maayu
the series circuit 100watt bulb are low resistance. so current will be in-cress that was the bulb make more heat
but the KWH is discress

Answer / priyam jain
We will not get as much heat as earlier as because the energy is utilized more now by the bulb then earlier and heater will get less energy.

Answer / vishak
Required heat will not get because the in the area of 60kw
we are placing 100kw at that time amount of current utilized
is increased .As the current drawn is increased then the
voltage will get drop . this will affect the heater
