2187help!!!! i bought a new house 2 yrs ago,ive just had 2 new lights fitted,when i boil the kettle,maybe 2 times in succession the safety light switch trips out,it dosnt do it straight away but it seems to do it when the kettle boils!!!!! sounds very odd to me
2 4201one conductor length is L.and i am strech uniformly this conductor and made length is 2L.so resistance of this strech conductor is R=4R..but i want to know about area of stech conductor hows it become a/2..
