The bulbs are connected in parallel, meaning the potential difference across each is 220 V, as voltage does not divide in a parallel circuit. The current drawn by the 100 W bulb is calculated as: Current = Power / Voltage. Current = \( \frac {100}{220} \) A. The current drawn from the line is the sum of the currents drawn by each bulb: \( I = \frac {100}{220} + \frac {60}{220} \).
\( I = \frac {160}{220} \)
\( I = \frac {8}{11} \)
\( I = 0.727 \ A \)
