    1000 W use karana electric equipment ekak 1 hour use karoth 1 KWh kiyala neda calculate karanne?

    Ehemanam 100 W bulb ekak 1 KWh ekak use wenna 10 hours pawichchi karanna oneda?
    50 W use karana ekak nam 20 hours use karanna oneda?

    Poddak kauru hari oke waraddak thiyenawada kiyala kiyanna puluwan da? waradi nam hari additional measurements oneda kiyala poddak kiyannako.

    ***Puluwannam oya case ekedi uda kiyapu equipment wala Amps usage eka KWh calculation ekata balapemak nadda?

    W = (I^2) R

    Which means, when you say `wattage`, that includes the current it takes. Usually the current flow variates throughout the usage of an equipment. ( Ex: fans take more current when starting up but less when running on a constant speed ). So the wattage is usually an average expression.

    For a rough calculation W * time is a good approximation.
