Given two light bulbs with the following ratings: 75.0W 120VAC and 100W 120VAC. They are connected in series across a potential difference of 120. VAC. Assuming that the operating resistances of the bulbs are not affectd by the series connection, calculate (a) the power produced in each bulb, and (b) the total power produced in the series circuit.(adsbygoogle = window.adsbygoogle || []).push({});

Using I=P/v gives (a) 75W & 100W and (b) 175W

is this correct?
