They say that nichrome is a better heating element as it has a higher resistance. But if I take V=RI then ain't I decrease since R is high, so current is lesser. Thus, resulting in a lower power dissipated as heat? Also, they aq if I use the wrong wires like thin wires, it will cause a lot of heat produced as thin wires has a lot of resistance. Using the same reasoning I don't get why higher resistance results in greater power... If current is constant then greater resistance results in greater power but I thought that voltage is usually constant? So when R increases, I will decrease and cause low power? Thanks for the help!
