What role does a resistor play in an electrical circuit? A. it removes excess electrons from the outer surface of a conducting wire. B. it transforms light energy and thermal energy into electrical energy. C. it transforms the electrical energy of the electrons into other forms of energy. D. it stores electrical energy until it can be released by closing a switch

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
