The resistance of a heater coil is 110 ohm. A resistance 
is connected in parallel with it and the combination is joined in series with a resistance of 11 ohm to a 220 volt main line. The heater operates with a power of 110 watt. The value of 
in ohm is
Text Solution
Verified by ExpertsThe correct answer is:
A
Power consumed by heater is 110 
so by using
.
Also from figure 
and 
. So 
Applying Ohms law for resistance
