1. You connect two coils of the same resistance in series to a constant-voltage line. When you later connect them in parallel to the same line, the heat developed per minute, compared with the former rate is(adsbygoogle = window.adsbygoogle || []).push({});

a) the same

b) twice as great

c) one half as much

d) four times as great

e) one fourth as much

Now this is what I was thinking... since the ratio of the Reff series to Reff parallel would be 4:1, which means that the resistance would be 4 times greater in the series circuit and the resistance is proportional to the amount of heat lost... therefore the heat developed per minute would be 4 times greater. And since we want the parallel comapred to former, so parallel(heat)/former(heat) = 1/4 = one fourth = e.

Is there a flaw in my way of thinking? Thank you for your time guys (or girls).
