the bill tarrif for each electric unti vary on urban or rurla area....suppose u r in lucknow then ur bill tarrif is 6rs per unit
...so calculation of bill for 900w
900watt mens .9kw
unit =kw *hour
1kwh power consumption=1unit
so for 1 hour>>>1*.9=.9unit
for 12 hours=.9*12=10.8unit
for 1 mnth=.9*12*30=360*.9
if tarrif is 6 rs per unit
jen 1 mnth bill=6*360*.9
