Answer;
=25.99 ohms
Explanation;
A month has 30 days equivalent to 720 hours.
1000 kwh is equivalent to 1000000 watt,
Then 1000000 watt divided by 720
wattage per hour=1388.9
Therefore;
Wattage/hr divided by line voltage is equivalent av. current
= 1388.9 W/hr รท 190 v
= 7.31 amperes
Assuming that the load is 'resistive' and not inductive
Resistance is voltage divided by current;
= 190/7.31
=25.99 ohms
