Hi guys, i would like to seek help to those who knows how to compute electrical consumption? computations will start from getting load from the electrical appliances. ex electrical fan, 40 watts bulb etc.... up to how to convert the consumption to pesos.

kaya ko po pala ito gusto malaman dahil po sa this coming month im be sharing my electrical meter to my cousin and due to that we want to compute how much electricity will be adding to my billing since may mga appliances siyang dala.

thank you in advance
