Both the bulbs are connected in parallel. Therefore, potential difference across each of them will be same that is 220 V, Current drawn by the bulb of rating 100 W is given byI=P/V =100/220=0.4545...ASimilarly, current drawn by the bulb of rating 60 W is given by =60/220=0.2727...A∴ the total current drawn from the line =0.4545+0.2727=0.727A .
