Answer:
please mark as brainliest
Explanation:
if we connect bulb to the metal wire and connect wire's end through the battery then, the bulb will glow . which shows that metal is good conductor of heat and electricity. Now if we connect bulb through a wooden scale, then bulb will not glow So ,this shows it is bad conductor of heat and electricity.
