Heat is produced in a heating element when the charge carriers (constituting the current) collide with the metal ions of the element. Heating elements are typically very short and require a specific resistance to produce heat (i.e. superconductors do not produce heat below the critical temperature since its resistance there is zero). For practical reasons (you do not want filaments to be too long), a good heating element should therefore have, Select one: O a. a high resistivity and low melting point O b. a high resistivity and high melting point O c. a low resistivity and low melting point O d. a low resistivity and high melting point Heat is produced in a heating element when the charge carriers (constituting the current) collide with the metal ions of the element.
